Quick Summary: Semi Formal Outfits
Short on time? A semi formal outfit usually means a midi or maxi dress, a blazer with wide-leg trousers, or a satin skirt with a polished top, plus a dressy shoe and one finishing accessory. Try the Mint Velvet satin cape maxi dress for a wedding, the black double-breasted blazer with wide-leg trousers for a dinner, or the Polo Ralph Lauren belted shirtdress for a chill daytime event. Add block heel pumps and you are done.
What Does Semi Formal Mean?
Semi formal is the dress code between casual and formal. It is dressier than business casual but less formal than black tie, so you can skip the floor-length gown while still looking polished. Think cocktail-length or midi dresses, satin skirts, tailored blazers with trousers, jumpsuits, and dressy flats or heels.
Semi formal outfits for women work well for weddings, holiday parties, graduations, church events, rehearsal dinners, and nicer restaurants. When an invitation says semi formal, cocktail attire, or dressy casual, this is the category to shop. Pants are absolutely allowed: a matching blazer and wide-leg trousers often looks more modern than a dress.
Semi Formal Colors That Work
Navy, forest green, burgundy, blush, black, cream, and soft white are the safest semi formal colors, and they photograph well in both daylight and evening light. Satin and crepe fabrics make rich colors look dressier. A white eyelet dress like the Maeve Mona maxi dress suits a daytime event, while black wide-leg trousers like the Longchamp pair work for a dressy dinner. Keep jewelry simple and let one piece carry the look.
