Semi-Formal Wedding Guest Attire 101
Just how formally are you supposed to dress for a semi-formal wedding? Semi-formal wedding attire is an extremely popular choice as far as dress codes go, but it's also one of the more ambiguous ones and the line between casual and semi-formal can seem awfully thin for the uninitiated. According to The Knot's Real Weddings Study, which surveyed more than 12,000 newlyweds who were married in 2022, 64% of couples opted to have a semi-formal wedding. Why? It's neither not too fancy nor too casual, a sweet spot that ostensibly takes the pressure off guests off all varieties.
Here's the simplest way to put it: semi-formal, which is sometimes known as "dressy casual," falls in between cocktail attire and black tie optional. While you won't need to show up in an evening gown or tuxedo, it's not a situation where anything goes, either. Below, we're outlining exactly what semi-formal wedding guest attire means for men and women, including some of the most common questions about this tricky dress code. We've also solicited expert advice and hand-picked several looks to inspire your choices when you're ready to start shopping.

What Is Semi-Formal Wedding Attire?
Semi-formal wedding attire is the murky middle ground between formal and casual. It usually requires some traditionally formal pieces but frees up the ways you can wear them. "There's one thing this dress code is not," notes The Knot's senior fashion editor Naomi Rougeau. "An invitation to slack sartorially." For suiting, dress shirts and ties aren't required, nor are matching suit pieces. You can mix and match suit separates, work a sweater into the outfit (a great option for fall or winter weddings), or leave your tie at home. For those wearing dresses, something in a midi-length is perfect, though you're also welcome to experiment with jumpsuits, rompers, and separates.
Rougeau notes that weather should play a part in how you piece together your semi-formal wedding outfit and that it's an opportunity for self-expression and experimentation. "A beautifully tailored linen suit would be ideal for a summer wedding in Sicily while a snowy locale calls for textured fabrics such as flannels and velvets" she says. "Try to shirk the business world connotations that most suiting conjures up; a semi-formal event is your call to embrace the ambiguity as well as creative flourishes such as a particularly vibrant tie, pocket square, lapel pin, or jewelry that you couldn't necessarily get away with at the office but that will make for a unique look."
Semi-Formal Wedding Attire 101
If you're wondering what to wear to a semi-formal wedding, you've come to the right place. This dress code comes with a million questions, occupying the space between formal and casual. You want to toe that line without crossing it too far in either direction. Here are some of the most common questions about semi-formal wedding attire.
Is semi-formal wedding attire the same as cocktail?
Semi-formal and cocktail dress codes are relatively similar, but they're not the same. You can think of semi-formal wedding attire as a slightly toned-down, business-esque version of cocktail attire. These two dress codes overlap in the sense that shorter dress hemlines (think midi-length and high-low skirts) and suits (versus tuxedos) are both appropriate. While cocktail attire is all about eye-catching patterns, colors, and statement accessories, semi-formal wedding attire is a little more understated. Solid, darker colors and subtle patterns, such as a classic floral print or stripe, are always safe bets for this dress code.
Can I wear a floor-length dress to a semi-formal wedding?
Traditionally, formal attire, black tie, and white tie are the only wedding dress codes that require floor-length gowns. When it comes to semi-formal wedding attire for females, we recommend mid-length or knee-length hemlines, which are more on par for this level of formality. If you do wear a floor-length dress, avoid choosing a style with beading or other elaborate embellishments, since those indicate a swankier affair (and you run the risk of being overdressed or upstaging the wedding party).
What shoes do you wear with semi-formal wedding attire?
Women should wear high heels or pumps though dressy wedges and heeled booties also work. If you're not a heels person, a nice pair of embellished sandals or classic flats are appropriate. Leather brogues, oxfords, loafers, and dress shoes are all good footwear choices for men attending a semi-formal wedding. Avoid sneakers (even if they're brand new) and stay away from flip-flops and casual boots.
Can you wear jeans to a semi-formal wedding?
Even though semi-formal is interchangeable with "dressy casual," you shouldn't take the phrase too literally. In general, we don't recommend wearing jeans for any type of wedding (even the most casual weddings, unless the couple explicitly allows denim), and especially not for a semi-formal dress code. Opt for dress pants or khakis instead, paired with a blazer or suit jacket and tie.
Semi-Formal Attire for Women at Weddings
When you're shopping for semi-formal attire for women, you can skip the evening gown and wear a cocktail dress instead. Dressy jumpsuits, rompers, and separates are also appropriate semi-formal wedding attire options. Finally, use accessories to your advantage: jewelry can elevate something on the casual side, while block heel sandals (versus rhinestone-covered stilettos) can tone down a fancier ensemble. If you're looking to shop around and explore, stores like Anthropologie, Reformation, and Nordstrom are going to have excellent semi-formal options. Here are some shoppable outfit ideas we love when it comes to semi-formal wedding attire for female guests.

Semi-Formal Attire for Men at Weddings
Unsure how to dress for a semi-formal wedding as a male guest? Relax, there's no need to worry about donning a tux or bow tie. The formula is super simple: a suit with a button-up shirt and dress shoes (though with the right suit, you can also get away with a turtleneck sweater). For daytime events, a blazer and slacks or a lighter suit are always reliable, but for evening weddings (or if you want to err on the side of caution), we suggest wearing a classic dark suit. Finish your look with a standard necktie—other accessories, like cufflinks, a pocket square, or a vest, are completely optional. Classic retailers such as Brooks Brothers, Men's Wearhouse, and J. Crew are your friends when it comes time to put together these fits. Shop our examples below for maximum efficiency::
