What is Trending For Semi Formal Wedding Attire in 2026?
In 2026, semi formal wedding attire is all about elevated prints, whimsical elegance, and vintage silhouettes. Here’s a quick breakdown of the top semi formal attire trends we can’t wait to wear this year:
- Playful prints: A semi formal dress code gives you room to play around with fun prints for your attire, like polka dots or graphic florals. The key is to balance a bold pattern with a simple and elevated silhouette, like this elegant dotted scarf dress.
- Whimsical details: The word of the year for wedding attire is whimsy, and that’s especially relevant for a semi formal dress code. Channel a romantic, whimsical aesthetic with sheer cape details, 3D flower accents, and playful ruffle dresses.
- Vintage-Inspired Silhouettes: This year, we’re leaning all the way into an elegant, vintage vibe with wedding attire inspired by past eras (think: Old Hollyhood and the Rococo period). For women, embrace drop-waist silhouettes, lace trims, and dramatic scarf accents. For men, keep it classic with double-breasted blazers, plaid prints, and retro dress shoes.
Semi Formal Wedding Dress Code FAQs
Despite being one of the most popular guest dress codes for modern-day weddings, semi formal wedding attire can still seem like a big question mark. But don’t stress. To help you dress to impress this wedding season, we’re breaking down all the must-know FAQs about what semi formal really means. From the best colors for a semi formal wedding to what not to wear for this dress code, keep scrolling for our complete attire guide!
What is Semi Formal Wedding Attire?
Semi formal wedding attire sits at the sweet spot between cocktail attire and a black tie dress code. It’s also commonly referred to as “dressy casual” — kind of like 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 feels too casual 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 dress code, 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 soft, neutral color 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 it’s a big no-go to wear 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 or 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 category, while suit jackets and dress pants are more dressy casual. Similarly, floor-length gowns are gorgeous for a formal wedding, while sophisticated midi dresses are perfect for a semi formal dress code.

What Should You Not Wear to a Semi Formal Event?
Sometimes, the easiest way to determine what you should wear for a semi formal dress code is by first figuring out what you shouldn’t wear. As we mentioned above, tuxedos and evening gowns are too dressy for semi formal wedding attire, as are pocket squares and glittery jewelry. In other words, if your outfit would look at home at a black tie event, it probably doesn’t qualify as semi formal wedding attire.
At the other end of the dressy spectrum, jeans are typically a no-go for a semi formal dress code. 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 coffee run probably isn’t a good fit for a semi formal wedding attire dress code
What Attire Colors Are Appropriate For a Semi Formal Wedding?
When it comes to the best colors for your semi formal wedding attire, you can’t go wrong with muted hues and pastel shades. This is also a bit of a balancing act — dark shades like black and charcoal generally feel too formal for a semi formal dress code, while bright and flashy colors are typically reserved for cocktail attire. We suggest playing it safe with soft colors that fall somewhere in the middle (like blush pink or navy blue).
When in doubt, you can also use the season as your color inspiration. Brighter colors are more appropriate for a spring or summer wedding, while darker hues are a go-to for the fall and winter. And if you do want to mix things up with your color choice, create some balance with a subtle print (such as bright florals on a black dress or a patterned button-down with a dark blazer) and strategic accessories. Which brings us to our next FAQ….
What Type of Accessories Should You Wear With Semi Formal Wedding Attire?
Now for the fun part! Just because a semi formal dress code 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.
Jewelry plays a bigger role in semi formal wedding attire than many guests realize. While your dress or suit sets the stage, the right accessories are what bring the entire look together. If your outfit is more on the casual side, dress it up with some statement jewelry (we love embellished earrings for moments like this) or a chic yet comfy pair of heels. For outfits that are leaning formal, tone it down with a simple tiny diamond necklace or trendy flats.
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 a semi formal dress code, a sleek watch and classy belt will always be in.
