A grandchild's wedding is a special and exciting event where you're likely going to receive a little extra attention. As grandmother-of-the-bride or -groom, you might be walking down the aisle as part of the extended wedding party or starring in a few important photos. Either way, you'll want to look and feel your best, and your outfit is a big part of that. A grandmother-of-the-bride or -groom pantsuit can be an elegant alternative to a grandmother-of-the-bride dress, and there are plenty of options to choose from.

Shopping for the perfect wedding pantsuit for grandmothers means, above all, finding something that you feel comfortable in. Pantsuits can feel a bit more versatile than a gown, and can still be just as formal. There is no official style etiquette for the grandmother-of-the-bride or -groom to follow, but you should always fit in with the wedding dress code. When in doubt, opt to be more formal over more casual—as a general rule of thumb, grandmothers tend to wear something similar to a dress the mother-of-the-bride or -groom might wear.

22 Best Grandmother-of-the-Bride & Groom Pantsuits

Pantsuits for the grandmother-of-the-bride or -groom should feel like a good fit with the rest of the wedding. If you know you'll be involved in some special parts of the ceremony or reception, you may want to consult the bride about wedding colors, any themes happening or what they might be envisioning. You may also want to check in with the other grandmothers in attendance to see what they're wearing. Select something that feels seasonally appropriate — for example, light layers are ideal for warmer weather. Below are some options for the big event.

It's hard to find something more versatile than this simple pantsuit. The blazer has an asymmetric hem that feels fun and whimsical, with an oversized belt for added interest and a flattering effect.

This three-piece suit offers a really comfortable fit thanks to a loose fit and elastic waist on the pants. The lace tank top is a nice contrast against the smooth pants, and while the matching lace jacket definitely makes this feel more formal, wearing the tank alone is great for warm weather weddings. The lace also features some sequins that give this a nice sparkle, and it's available in an array of colors.

Size Range: 14W - 22W

It's available in a lot of different colors and you can remove the cape to feature a top with cap sleeves if you'd like.

Size Range: 0 - 30; Custom Sizing Available

With straight-leg pants designed to hit right at the ankle, you'll have the perfect opportunity to show off a pair of statement-making shoes.

Size Range: 00 - 18

With sequin detailing at the sleeves and a deep midnight hue, this two-piece set is perfect for a formal affair. It's made from flowy satin crepe, which means it's equal parts elegant and comfortable. Add a little extra shine with metallic shoes and jewelry, or keep things minimal with all-black accessories.

Catherines 2-Piece Beaded Mesh Sleeve Pant Set

Although super basic at first glance, it's the glittering mesh sleeves that really make this pant set stand out. The sheer sleeves feature strands of sparkling beads, and it's one of the few pantsuits that offer a long sleeve top. The pants have a comfortable elastic waist and an overall flowy feel and the tunic-style top has an asymmetrical hem for added interest. It's available in three different colors and is a great choice for a chilly winter wedding.

Size Range: 0X/L - 6X

Lela Rose Floral-Print Top & Straight-Leg Ankle Pants

If your goal is to wear something unique and eye-catching, then this is the pantsuit for you. The bold and colorful florals would be beautiful for a fun spring or summer wedding. Slim, straight-leg pants and a chic boat neck sleeveless top offer a different silhouette than many other formal pantsuits, and a nipped in waist means it's a bit more fitted. Keep in mind that as stylish and elegant as this is, the bright pattern means it might not fit in at a very formal, black-tie wedding. That said, each piece is versatile enough to be paired with other clothing for different events.

Size Range: 2 - 16

If you love the idea of a pantsuit but don't love the idea of multiple pieces, then this pink one-piece could be a beautiful choice.

This certainly isn't your typical grandmother- or mother-of-the-bride pantsuit: It shows off a sliver of your belly through the sheer overlay of the top. And if you're comfortable with that, then who says you can't wear this to a grandchild's wedding? The glitter mesh fabric, floral embroidery and bow sash at the waist all make this a very feminine look, and the wide leg trousers offer plenty of comfort.

Size Range: 0 - 30; Custom Sizing Available

Emerald green may not always be the first hue that comes to mind when you think of a grandmother-of-the-bride wedding dress, but it's a gorgeous choice that will really make you stand out. These two separates can be worn together or on their own, as they're very versatile. The lightweight pants have a comfy belted waistband and wide fit, while the top has stunning puff sleeves, a button front and fun gold hardware.

This stretch crepe jumpsuit should have a soft, pleasantly heavy feel that is still breathable. It's a great option for those who mostly want to keep their arms covered but also want some flexibility: the cape style sleeves are a bit more relaxed than a jacket. This features an overall more fitted look, with pants that flare out a bit and a v-neck top. It's available in a wide range of colors and styles, so it should work for anyone.

If you're headed to a more casual wedding but still want to feel dressed up for the event, this pantsuit is a nice choice: it's on the more formal side, but it's still low-key. When the jacket is removed, this is even more casual (in a good way). The sleeveless top features a pretty floral pattern and sparkles along the neckline, while the loose-fitting jacket features the same pattern. And the blue color it comes in is surprisingly versatile.

Size Range: 14W - 24W

Sachin & Babi Morgan Top and Alli Satin Pant

This eye-catching set offers a glam vibe that will look beautiful in every photo you're in.

You'll feel so comfortable in this pantsuit that you won't mind wearing it for hours on end… even if you hit the dance floor. Made of a lightweight, stretchy fabric that is soft and comfy, this isn't clingy and has a cool feel to it. The beaded trim on the cardigan makes it feel more special, but you can also pull it off to wear just the tank and pants if you'd like. The layers make this a great year round choice.

Size Range: 16W - 34W; Petite Sizes Available

This stunning jumpsuit features short dolman sleeves, wide-leg pants and a flattering mock neckline, making it a perfect pick for a fall, winter or holiday wedding. The rich burgundy hue is statement-making without feeling over the top, and the velvet fabric adds even more interest (and warmth).

Although this is a jumpsuit and not technically a pantsuit, it does resemble one, making it a nice option for those who would prefer a one-piece. Stylish and sleek, this has a structured design with a flowing asymmetrical bodice and long wide-leg pants. The black color makes it even more versatile and easy to wear, and the overall style is so nice you really don't need many accessories.
