Bringing little kids (like babies and toddlers) to a wedding can be a little stressful, from working around their nap times to figuring out how you're going to feed them. One thing that doesn't have to leave you feeling overwhelmed, though, is picking out the perfect toddler wedding outfit. We've put together a guide on exactly what they can and should wear, and we've also hand-picked some especially cute options you can order online right now.

Weddings typically call for more formal attire, even for the little ones, so you'll want to opt for some special occasion clothing here – think fun party dresses and the cutest mini suits you've ever seen, with some cute children's wedding shoes too. Older toddlers will be excited to dress up, and as long as infants are comfortable, they'll be in prime photo op outfits. Take a look at the below options that include something for everyone, whether you want to splurge on a fancy look or go for something that's just as cute and more budget-friendly.

Tips for Choosing Kids Wedding Outfits

The best baby and toddler wedding outfit is special occasion attire that is still comfortable. While weddings typically call for formalwear, the guests of honor are bound to be more understanding when it comes to what your little ones are wearing. They should be more dressed up than they would be on an everyday basis, but you also want to make sure their clothing is comfy and functional (a toddler who hates what they're wearing? It's not the ideal situation). Keep the below in mind when shopping.

Check the dress code.

Follow the dress code as much as possible. If you're heading to a black-tie or black-tie optional event, go for a button-down and slacks or even a little mini suit, or a fancy dress with some detail. For a more relaxed setting, like a daytime wedding or something outdoors, opt for party dresses or even a nice romper or jumpsuit. No one is going to be upset if the kids are slightly off dress code, but avoid something very casual, like a onesie and sweats. And even though these are kids, try to avoid having them wear only white. It could unintentionally make them look like part of the wedding party. White dresses with prints or white button-downs are fine, just avoid a totally white look.

Consider the season and venue.

Remember: comfort is key for little ones, which means you definitely need to dress them for the weather. If it's going to be warm out, choose lightweight fabrics that breathe and allow them to move around a lot without getting sweaty (you can't go wrong with linen and cotton). Avoid extra fabric, like unnecessary jackets, tights, or heavy tulle skirts. For cooler weather, opt for fabrics that will keep them warm, like wool or velvet (cotton is still a good option here). Bring layers too, like a matching cardigan sweater for a dress or a suit jacket or sweater for a shirt and pants. And for an infant, a neutral and luxe blanket is always acceptable.

The venue is important too. If you're going to be outside, make sure their shoes are up for the task: nothing white that can be destroyed too easily. Keep layers on hand too, even if it seems warm out.

Ensure on and off ease.

Whether your kids are potty trained or still wearing diapers, you'll want an outfit that can easily be removed when necessary. For babies, try to pick dresses or pants with snaps for quick diaper changes. For toddlers, avoid unnecessary details like complicated buttons or zippers.

Choose comfort (for baby and you!).

A baby or a toddler is going to be miserable in an outfit that just isn't functional or that feels scratchy, too tight or too bulky. Sometimes party dresses or fancy frocks can be a little itchy on a baby's skin, so have them wear a onesie underneath for extra comfort. Make sure you have them try on their clothes well in advance so that they can tell you if something is bothering them (or you can tell they don't like it).

Make it special.

There's no reason this can't be a fun experience for everyone. Make older toddlers feel special about wearing a new outfit to a wedding by showing them that their fancy look is just like all the adults. Pick a dress that your baby or toddler wouldn't normally wear, like something with a tulle skirt or sparkly details. This is a time to put them in something really adorable that you might typically skip over, so pick something you love.

Where to Buy Baby and Toddler Wedding Outfits

There are plenty of places to find baby and toddler wedding outfits, and picking the right place to shop depends on the style you're looking for and your specific budget. The below are some of our favorite picks.

  • Janie and Jack: For chic and sophisticated options, check out Janie and Jack. The retailer sells clothes that are so stylish you might even want them for yourself, as well as matching accessories and shoes to create a full look. They have a wide variety of frilly frocks that feel extra special, as well as tiny blazers and suits. The price point is a little higher here, usually between $50 and $110, although you can shop sales fairly often.

  • Bloomingdale's: If you're not sure what you're looking for, Bloomingdale's is a great place to start, as they have a wide variety of different styles and brands. You'll find plenty of Ralph Lauren for some classic looks, but also brands like US Angels and Peek Kids. They have dresses that are more casual and more dressed up, as well as some fun formal separates for boys. The price point here does tend to be over $50 and can go pretty high.

  • H&M: H&M is a great budget-friendly option for those who want something nice without spending a lot. This is a great retailer for inexpensive little suits and matching blazer and pant separates, as well as basics like neutral button down shirts. They have cute party dresses for babies that still feel functional and comfortable formal attire for baby boys as well.

  • Ivy City Co: This online shop caters more to little girls than boys, although they do have some boy options as well. They make mostly dresses and special occasion rompers, in a lot of different styles, patterns and colors, and all of the options feel special. They also offer a lot of mommy and me matching moments, if you're interested in that. The price range is generally between $50 and $110, so it can be pricey.

  • Target: Target has a wide variety of brands, from Carter's Just One You to Honest Baby and Grayson Collective. The prices are almost always budget-friendly, and they have plenty of dresses and formalwear to choose from. The pieces tend to be a little more casual, but you can still find plenty of suitable wedding options.

Toddler Dresses for Weddings

There's no shortage of cute toddler dresses out there, so picking just one is really going to be the tough part. Opt for a feminine floral for a spring or summer wedding, or do something more simple and versatile that you'll want them to wear again and again.

Hanna Andersson Baby Woven Shirt Dress

A floral dress is a toddler wedding outfit staple, and we love this version from Hanna Andersson. The comfortable woven shirt dress features a red, pink, and green floral print with a navy blue backdrop. Its collar and buttons are also great features that will make this dress stand out from the rest.

Size Range: 0-24M to 3Y

Boden Bow Tie Vintage Dress

With a touch of vintage flair, this floral dress feels unique and unexpected. The bright colors and design make this a perfect dress for a spring or summer wedding, and the orange belt with the front bow really adds something. Made of cotton and linen, it's a lightweight option that will definitely catch the eye.

Size Range: 2-3Y to 11-12Y

Carter's Purple and Coral Floral Sleeveless Sateen A-Line Dress

Muted watercolor style florals make this dress look different than so many other floral designs. It's made of a cotton taffeta that elevates it to be more than just a sundress. The cutout and bow in the back are special details, and at less than $20, you really can't go wrong with this choice.

Size Range: 3T-5T

BCBG Girls Lace Puff Sleeve Dress

Even toddlers can benefit from owning a great little black dress. This lace black dress is a good pick for the toddler who has more than one special occasion coming up. It's versatile and would work for any season (add tights for chillier weather), with a really pretty lace detail and fun puff sleeves.

Size Range: 2T-5T 2T-6X

Ivy City Co. Mini Cloud Nine Dress

Plenty of chevron ruffle details on the skirt and sleeves of this dress make it look like the princess style dream dress every toddler wants. It comes in three different colors (lilac, powder blue and champagne shade) and is perfect for a more formal wedding. The stretchy fit makes it comfortable and the loose skirt makes twirling ideal. It also comes in matching adult sizes as well.

Size Range: 12-18M to 11-12Y

Janie and Jack Satin Bow Dress

This soft pink satin dress is a classic that you could definitely have your toddler wear more than once. Aside from a bow in the front, this is a super simple dress that feels really versatile: add tights and a cardigan for fall and winter weddings, keep it bare for spring and summer. It has the prettiest scoop back detail as well.

Size Range: 6-12M to 12Y

H&M Sequined Dress

If there was ever a time for a toddler to wear a full sequined dress, it would be a special wedding. This glittering dress has a slight flare in the skirt, with loose sleeves and a comfortable fit all over. The gold would be so pretty at any time of year, but really screams winter wedding, while the bright pink option is great for warmer weather.

Size Range: 2T to 10Y

Toddler Boy Wedding Outfits

Toddlers don't have to wear a full suit to a wedding, but it is definitely a really adorable look. Be sure to pick comfortable pants with an elastic waist and have fun with the more laid back styles.

Janie and Jack Wool Suit Blazer and Twill Pants

If you want your toddler to be dressed up but don't want to put them into a suit, go this route: a suit blazer with twill pants and a button down shirt. It's a little more comfortable and laid-back, and is especially ideal for a daytime wedding. Plus, Janie and Jack sells an entire look to make styling a breeze.

Size Range: 6-12M to 12Y

Boys' Seersucker Blazer and Stretch Breaker Pants

This eye-catching seersucker suit was made for a spring or summer wedding and truly has to be one of the most adorable options out there. In a beautiful "bayside blue" this blazer has a matching stripy pants and can be paired with a lovely white shirt and suede shoes.

Size Range: 2-4T to 7Y

H&M Four-Piece Cotton Set

Model wearing a blue shirt, black bow-tie, and a pair of classic suspender pants

For a more laid-back wedding during the warmer weather (think a destination beach wedding or a small backyard soiree), you can ditch the blazer and opt for something easy, like a pair of sneakers with this formal shirt and suspenders. This lightly stiped blue shirt comes with a cute matching bow tie, and a pair of stretchy pants, which are comfortable and easy for them to run around in.

Size Range: 2-5T to 10Y

H&M Shirt and Chinos

Don't think your little one will wear a blazer or jacket? Go with this shirt and chinos look that's all put together for you. The pants are really functional, with an elasticized waist and mock fly, and the shirt comes with a removable bow tie. This would work for any season and can be made to look more formal with the addition of a jacket.

Size Range: 6M to 4T

Van Heusen Boys 4pc Suit Set

If you're not looking to spend a lot on something they may end up wearing only once, this set is perfect. For less than $50, you get a vest, pants, shirt and clip-on bowtie that makes up a pretty formal look. The pants have a fully elastic waistband for ease and comfort, and the polka dot shirt feels a little bit whimsical.

Size Range: 2T to 5T

Gymboree Special Occasion Bisquit Suit

If you're going to a more formal wedding in the spring or summer, this cookie-cream suit is a great choice. You can opt for the vest and blazer, or just one or the other, and you can also play around with color with a light pink shirt and add a fun bow-tie to the mix.

Size Range: 12-18M to 12Y

H&M Black Jacket, Suit Pants and Shirt

Make their look timeless with a classic black and white suit option: black suit jacket and pants with a crisp white button down. It's easy and they'll look wedding-ready whether the dress code is super formal or not. The pants have an elastic, adjustable waist for comfort, making this pretty functional for a suit.

Size Range: 2T to 10

Infant and Baby Girl Dresses for Weddings

For really little babies, put comfort and versatility above all else—luckily, you can still find plenty of cute designs. Opt for dresses that come with matching bloomers to cover their diapers or have built-in bodysuits. Soft and lightweight materials are also a must.

Hudson Baby Infant Girl Cotton Dress, Cardigan and Shoe Set

This set has everything your infant needs to go to a wedding: a cute dress and a matching cardigan in case it gets chilly. And while babies under the age of one definitely don't need shoes, they do make the outfit look even more adorable. This is made of soft cotton, it's comfortable, and diaper changes are really easy.

Size Range: 0-3M to 12-18M

Luli & Me Girl's Floral Smocked Dress

Made of a blend of cotton and polyester, this short-sleeved sundress is perfect for spring or summer weddings. It has a whimsical floral print that is subtle and sweet, as well as a cute Peter Pan collar.

Size Range: 6M to 10

H&M Tulle Dress With Bodysuit

Dresses on babies can be frustrating, especially when they aren't walking yet—babies are wiggly and squirmy, and the dress can easily ride up or just seem uncomfortable. This tulle dress has a pink bodysuit built into it to cover up the baby's diaper (with snaps to easily do changes) and a cotton top to stay comfortable. It's sweet and very versatile.

Size Range: PM to 9M

Hill House Home The Baby Ellie Nap Dress

Nap dresses took the world by storm during the pandemic—and now they come in a mini size! The baby nap dress is available in several colors and patterns, and offers elasticized smocking, ruffled shoulders and matching bloomers. It's perfect for a wedding in the springtime or really, any time of year.

Size Range: 6-18M to 2M

Ralph Lauren Ruffled Dress and Bloomer Set

If your baby's comfort is more important to you than anything else, opt for this lightweight cotton set from Bloomingdale's. It's soft and comfortable, easy to get on and off, and comes with a matching diaper cover. The little ruffles along the collar make it feel more special, but this will feel more like a fancy pair of pajamas than something too frilly for them, and it's great for really little ones.

Size Range: 3M to 24M

H&M Collared Velour Dress

Velour is a slightly heavier fabric that is a great choice for fall or winter weddings. This bold floral print uses unique colors and a fun design to stand out, and the large collar adds a stylish touch without feeling overwhelming. It's soft and comfortable, and you just need to add a pair of tights to make it a full outfit. It also comes in two pastel colors if this darker one isn't working for you.

Size Range: 6M to 4T

Infant and Baby Boy Wedding Outfits

While mini suits are adorable for little babies, they can also be a little uncomfortable. Go for a suit style outfit that's made with a bodysuit for comfort, and choose one that doesn't have a lot of layers. Fancy rompers are also a great choice, especially for newborns.

Cat & Jack Baby Boys' Suspender Set

It doesn't get much cuter than a suspender set on a newborn baby. This outfit comes with a shorts, striped suspenders, a short-sleeve and button-down bodysuit for comfort. Crotch snaps on the bodysuit make diaper changes easy, and there's no need for a bulky jacket here.

Size Range: NB to 24M

Janie and Jack Baby Pique Polo Romper

As adorable as the teeny tiny suit sets are, they aren't very practical for a newborn, especially before six months of age. This polo romper is nice enough to be worn in a more formal setting, with its little collar and cotton pique fabric, but it will also keep your baby comfortable and happy.

Size Range: 0-3M to 18-24M

Carter's Baby Boys 3-Piece Bodysuit Set

This three piece set is perfect for a spring and summer wedding, especially if it's supposed to be pretty hot outside. The little pants have a nautical feel with anchor patterns and a tan shade. The rest of the outfit features a pair of blue suspenders and a button-down shirt, great for easy changes.

Size Range: NB to 3M

Nordstrom Kid's Bodysuit, Shorts and Bowtie Set

If you're looking for something more formal, but you don't want to attempt an actual suit, this baby version is so cute. The button down bodysuit is great for quick changes, and the shorts have an elastic waist that makes them easy to take on and off. It even comes with a cute little bowtie.

Size Range: NB to 18M

Dressy Daisy Baby Boy 5-Piece Formal Tuxedo

If a formal tuxedo is a must for everyone on the guest list (even the littlest ones), this mini tux definitely fits the bill. The set includes a jacket, shirt, bow tie, pants and vest, and comes in 11 colors, from classic black to casual khaki. And with 4,000 reviews, it's certainly a popular choice.

Size Range: 3M to 4T

Ralph Lauren Boys' Gingham Linen Bubble Shortall

Another easy romper, this bubble shortall has a more dressed up feel and is great for a special occasion like a wedding. The linen fabric makes it lightweight and ideal for warmer weather, and the touch of blue is such a nice shade. This is a little pricier, but it's a well-made piece that is meant for hand-me-downs, and it's very versatile.

Size Range: 6M to 24M

H&M 2-Piece Formal Set

White body suit with a lovely bowtie, cream vest and a matching pants

A comfortable white bodysuit with a collar makes this a great choice for a baby. The vest looks like a separate piece, but it's attached to the bodysuit so you don't need to worry about layers getting in the way of anything. The pants have an elastic waistband and make this perfect for any season.

Size Range: PM to 9M
