When I first got my invitation to a semi formal wedding, I was excited but also a little confused. Semi formal is one of those dress codes that sounds straightforward but feels like a gray area in practice. It’s not as relaxed as cocktail attire, but it doesn’t require the full elegance of black tie. Over the years, I’ve attended many semi formal weddings—some in fancy ballrooms, some in sunny gardens—and I’ve finally figured out what works and what doesn’t. In this guide, I’m sharing exactly what I wear, how I choose my outfit, and where you can shop the pieces I love.
Why Semi Formal Dress Codes Can Be Confusing
Understanding the Difference Between Semi Formal and Formal
When I first started shopping for wedding outfits, I mixed up semi formal and formal all the time. The easiest way I explain it to friends:
- Formal: Floor-length gowns or tuxedos.
- Semi Formal: Knee-length to midi dresses or suits. No tuxedos or gowns needed.
So, think polished but approachable. You’ll look elegant without feeling overdressed.
How the Time of Day Affects What You Should Wear
One tip I learned is that the time of day can guide your outfit. Afternoon weddings can feel lighter and a bit more casual, so softer colors and breezier fabrics work best. Evening weddings often feel a touch dressier—think deeper colors, richer fabrics, and a bit more sparkle.
Choosing the Right Outfit for Women
After trying dozens of dresses over the years, I’ve learned to look for these qualities:
- Comfortable but structured fabric
- Midi length for versatility
- Simple silhouettes that still feel special
Here are some of my favorite options you can order online:
Elegant Dresses: Midi vs Knee Length

For my last summer wedding, I wore this lovely LuckyFash Semi-Formal Chiffon Midi Dress. The chiffon fabric moved beautifully, and the soft blue felt romantic without being too bold. Midi length gives you plenty of coverage while still feeling light.
Fabrics That Feel Dressy But Not Overdone

Satin can feel fancy but approachable. For cooler months, I’d recommend the LuckyFash Seasonal Midi Satin Dress in navy or dark yellow.
Necklines and Sleeves: What Feels Appropriate

I love a dress with a little structure at the neckline, like a modest v-neck or a square neckline. For instance, the LuckyFash Deep-V Swing Midi Dress is elegant and flattering without showing too much.
Jumpsuits and Dressy Separates I Love
If you’re not a dress person, don’t worry—tailored jumpsuits are a fantastic alternative. Look for a structured waist and clean lines. While I didn’t buy a jumpsuit for my last wedding, I’ve seen many guests in navy or jewel-toned pieces that looked polished.
Accessories to Elevate Your Look
I always add:
- A metallic clutch (gold or silver)
- Statement earrings
- A dainty bracelet or watch
These details take any simple dress up a notch.
Shoe Styles That Balance Comfort and Style
The secret to surviving a long ceremony and reception is a pair of mid-height block heels. They look sophisticated and keep you comfortable on the dance floor. Nude or metallic shades are my go-to.
Picking the Perfect Look for Men
Shopping for men’s semi formal outfits can feel simpler—until you start comparing suit styles. I’ve helped my partner shop multiple times, and here’s what works:
Suit Colors That Work for Semi Formal Weddings


Light gray and navy are my top picks. For summer weddings, the Classyby Sky-Blue Linen Blend Suit is breathable and looks crisp. In fall, a darker suit like the Classyby Light-Gray Semi-Formal Suit feels seasonally appropriate.
Shirt and Tie Combinations I Recommend
I usually recommend:
- White shirt + patterned tie for daytime
- Light blue shirt + solid tie for evening
- No tie with a pocket square if the invitation allows
When a Blazer Is Enough (and When It’s Not)

If the wedding is very relaxed, you can wear a blazer with dress pants. My favorite find is the Coofandy Slim-Fit Sport Coat for under $80.
Shoe Choices: Oxfords, Loafers, or Dress Boots
Leather Oxfords are always safe. For outdoor weddings, brown loafers look less formal but still polished. Just make sure they’re clean and polished.
What to Avoid Wearing
Too Casual: Jeans, Sneakers, and T-Shirts
Even if the wedding is outside, jeans and sneakers will look out of place. Save them for the after-party.
Too Formal: Tuxedos and Gowns
Tuxedos are reserved for black tie, and floor-length gowns can feel over the top.
Patterns and Colors That Distract
I avoid loud prints or neon colors that draw too much attention. Subtle patterns are fine.
Considerations for the Season
Spring and Summer Fabrics and Colors
Light fabrics like chiffon, linen, and cotton are your best friends. Pastels and muted florals are lovely choices.
Fall and Winter Layers and Rich Tones
Velvet blazers or heavier fabrics in burgundy or emerald look stunning in colder months.
How to Add Personality to Your Outfit
Statement Accessories That Still Feel Polished
A bold tie, a patterned clutch, or unique jewelry can make your outfit feel special without overdoing it.
Subtle Prints and Textures I’ve Tried
I love textured fabrics—like jacquard or crepe—that catch the light in photos.
Tips for Staying Comfortable All Day
Choosing Breathable Materials
Even if a dress is beautiful, if it doesn’t breathe, you’ll regret it halfway through the reception. Always check the fabric content.
Packing a Backup Pair of Shoes
I learned this the hard way. A simple pair of flats or foldable slippers will save your feet after hours of standing.
Final Thoughts: How to Feel Confident and Stylish
At the end of the day, semi formal wedding outfits are about finding the balance between dressed up and comfortable.
Whether you choose a flowy LuckyFash Chiffon Dress or a tailored Bonobos Blazer, the key is feeling like yourself.
