So, you ripped open your latest wedding invite and saw the words semi-formal attire. Cue the group texts and the Google searches! If you’re asking yourself (or all your besties) what does semi-formal mean for a wedding, you’re definitely not alone.

With modern couples getting creative with everything from coastal formal to garden glam, wedding guest dress codes can feel like a riddle. But the good news? Semi-formal is one of the more approachable, flexible styles. It’s just about finding the right balance between relaxed and refined. Let’s decode it together and take the stress out of figuring out what to wear to a wedding when semi-formal is the rule of the day.

What Is Semi-Formal Wedding Attire?

Semi-formal is best described as that sweet spot between formal and casual. Believe it or not, it’s actually a step below cocktail attire—think less party-ready, more classic. While cocktail looks tend to be a bit trendier, semi-formal leans traditional with timeless silhouettes and a softer polish. In 2025, the vibe is elevated ease: polished, modern, and cool (without trying too hard).

For women and non-binary guests:

• Try a drop-waist slip dress, asymmetrical midi, or a satin column dress for an effortless, current look
• Sheer sleeves, soft shimmer fabrics, and subtle cutouts are trending—just keep it tasteful for the setting
• Don’t sleep on separates! Tailored trousers with a corset top, a sculptural blouse with a bias-cut skirt, or matching two-piece sets strike the perfect balance of fashion-forward and event-appropriate
• Accessories like sculptural earrings, micro shoulder bags, or ballet flats with a twist (think satin or a boxy square toe) complete the look

For men and masc-presenting guests:

• Go for a relaxed, tailored suit in a soft neutral, navy, or even a muted pastel if it’s daytime
• A crisp open-collar shirt works in place of a tie for most semi-formal settings
• Leather loafers, suede brogues, or a minimalist dress sneaker can all work depending on the venue; just keep it clean and intentional

Semi-formal doesn’t mean boring. With a little thought, you can show up looking on-trend and totally wedding-appropriate.

Dress Code Hierarchy: Where Does Semi-Formal Fit?

Still not sure where semi-formal fits into the wedding dress code org chart? Here’s a quick rundown of the typical ladder:

• White Tie: Ultra-formal. Floor-length gowns and tuxes with tails.
• Black Tie: Very formal. Tuxedos and evening gowns.
• Formal/Black-Tie Optional: Fancy but flexible. Suits or tuxes, long gowns or elevated cocktail dresses.
• Cocktail: A step above semi-formal. Shorter, trendier, party ready.
• Semi-Formal: Polished and classic but not overly dressed up.
• Dressy Casual: Relaxed but tidy. Great for daytime vows or outdoor venues!
• Casual: Think sundresses, khakis, or flowy separates. Note! Only appropriate when clearly and explicitly stated.

Do’s and Don’ts of Semi-Formal Wedding Guest Attire

✅ DO: Consider the venue and time of day. Daytime calls for lighter tones and fabrics, while evening leans darker and dressier.
✅ DO: Show off your personal style with accessories or standout details.
❌ DON’T: Confuse semi-formal with business casual—it’s a celebration, not a conference!
❌ DON’T: Show up in jeans, sneakers, or anything that reads “everyday errand.”

When in doubt, always show up one step dressier than you think. You can never be overdressed! (Unless of course you show up in white tie… that might be overdoing it a touch).

What to Wear: Semi-Formal Approved

From the chic city rooftop to a countryside chapel, semi-formal weddings can take many forms. Whether you’re channeling that elevated ease or adding your own modern touch, these guest-ready styles from David’s hit the just-right balance of refined, polished, and not over-the-top—exactly what semi-formal calls for.

For the Trendsetter: Slip into a slinky satin midi with a 2025-forward drop waist or cowl neckline. Pair it with minimalist heels and sculptural jewelry for a “quiet luxury” vibe that still turns heads.

For the Daytime Guest: Opt for a romantic two-piece set or in a breezy skirt in a soft floral. Bonus points for matching accessories and a sleek bun.

For the Evening Crowd: Go for a satin or crepe midi with an asymmetrical neckline or soft puff sleeve. Deep tones like navy, forest green, or plum feel just right after dark.

For the Non-Traditionalist: Go bold with a structured jumpsuit, a tulle midi skirt paired with a corset-style top, or a tailored pant set in black or ivory. (Yes, black is absolutely OK for weddings—just keep it festive!)

No matter the venue or season, the key to semi-formal is keeping things polished without going overboard. Look for pieces that feel modern yet effortless, i.e. styles you might actually want to wear again!

TL; DR

So, what does semi-formal mean for a wedding? At the end of the day, it’s all about looking put-together without going full tux or ballgown. It’s that sweet spot: Refined, comfortable, and ready to hit the dance floor. Whether you show up in a breezy midi, a sleek set, or a suit with some personal flair, just keep it polished, intentional, and a little bit you.
