We love any excuse to rock a new look, and a wedding is one of the best opportunities to try out the latest trends (neon pink, anyone?) or go a little glam. But, when the dress code calls for semi formal wedding attire, it can be difficult to know where the (hem)line is. How formal is too formal? Are jeans allowed? Is there such a thing as too many sparkles?

With more and more couples opting for semi formal weddings, now’s the time to get up-to-date on this ambiguous attire dress code. With wedding season fast approaching, don’t stress! We’re digging into what semi formal wedding attire really means — so you can focus on finding the ‘fit that makes you stand out for all the right reasons, and not the wrong ones.

Plus, we’ve rounded up some stunning semi formal wedding attire for both men and women that have us counting down the days for our next wedding invite.

What is Semi Formal Wedding Attire?

Semi formal wedding attire sits at the sweet spot between understated dressy and elevated casual. It’s also commonly referred to as “dressy casual” — which can be viewed as a weekend version of business casual. Think: flowy dresses, simple suit jackets, and timeless silhouettes.

For colors, prints, and hemlines, semi formal wedding attire doesn’t have strict rules like other dress codes, making it tricky to know what’s appropriate. We suggest factoring in the season and wedding venue to gauge what type of outfit is best. After all, a yellow mini dress may be perfect attire for a summer backyard wedding, but feel too flashy for a winter soiree in an elegant ballroom. It’s hard to go wrong when you dress specifically for the event!

To complete the semi formal wedding attire vibe, we recommend a natural, polished beauty look. That means you can skip the time-consuming updo and let your hair down (literally) with loose waves. And while we love a smoky eye, give your sparkly evening palette a rest and try a neutral color or simple wing instead.

GWS Semi Formal Wedding Attire Tip: When in doubt, go for the dressier option. While every couple may have different interpretations of what semi formal wedding attire means, most will appreciate the extra effort you took to dress up for their big day. So, if you’re deciding between khakis or slacks, we say nice dress pants never killed anyone.

Formal vs Semi Formal Wedding Attire

While you don’t want to ruffle feathers by dressing in ultra casual attire for a semi formal wedding, you also don’t want to go too far in the other direction. But where is the line between formal vs semi formal wedding attire?

With formal wedding attire, also known as black tie optional, guests will be dressing to the nines. For this dress code, you can expect elevated evening looks and luxe accessories that would be out of place in a casual setting. A semi formal wedding attire dress code, on the other hand, is one or two steps below that — less glitz and glam, more relaxed and refined.

For example, tuxedos fall in the black tie optional category, while suit jackets and dress pants are more dressy casual. Similarly, floor-length gowns are gorgeous for a formal wedding, and sophisticated midi dresses are perfect semi formal wedding attire.

What Should You Not Wear to a Semi Formal Event?

Sometimes, the easiest way to choose what you should wear to a semi formal wedding is by first figuring out what you shouldn’t wear. As we mentioned before, tuxedos and evening gowns are too dressy for semi formal wedding attire, as are pocket squares and glittery jewels. In other words, if the outfit would be at home in The Great Gatsby or Bridgerton, it probably doesn’t qualify as semi formal.

At the other end of the dressy spectrum, jeans are typically a no-go for a semi formal celebration. The same goes for t-shirts and most tennis shoes (although a trendy pair of sneakers could be elevated with a sophisticated suit). Think of it this way: anything that would make it on your Saturday afternoon coffee run probably isn’t a good fit for a semi formal wedding attire dress code.

What Type of Accessories Should You Wear With Semi Formal Wedding Attire?

Now for the fun part! Just because semi formal wedding attire doesn’t call for the bling of black tie or the endless options of a casual wedding, that doesn’t mean you can’t be playful with your accessories.

If you outfit is more on the casual side, dress it up with some statement jewelry (we love tassel earrings for moments like this) or a chic pair of heels. For ‘fits that are leaning formal, add some personality with a birthstone necklace or Euphoria-inspired nails.

When accessorizing suits, ties are not mandatory — but if the mood strikes, don’t be afraid to choose something with a bit of color. For shoes, dapper is always better, so we recommend a classy pair of dress shoes, oxfords, or loafers. And, while pocket squares and cufflinks are out for semi formal wedding attire, a sleek watch and classy belt will always be in.
