What semi-formal means
Semi-formal sits between a date party and a formal. It's dressier than a going-out look, but you don't need a floor-length gown. Think polished: a dress with structure or a nice fabric, worn with heels or dressy flats.
| Dress code | What to wear |
|---|---|
| Casual or date party | A fun mini, a set or a theme look (see date parties) |
| Semi-formal | A knee-length, midi or polished mini dress |
| Cocktail | Much the same as semi-formal, often a little sharper (see cocktail dresses) |
| Formal or black tie | A floor-length gown (see formal dresses) |
What to wear to a semi-formal
- Length: knee-length and midi are the safest choices. A polished mini works for a college semi-formal at night.
- Fabric: satin, silk, crepe, jacquard, brocade or lace look dressier than cotton or linen.
- Color: anything goes. A little black dress always works, and jewel tones and florals are easy ways to stand out.
- Shoes: heels, block heels or dressy flats, especially if there's dancing.
- Skip: sneakers, denim, anything that looks like a beach cover-up, and a full gown unless the invitation says otherwise.
Semi-formal by event
- Chapter semi-formals: a polished mini or a short satin dress. Ask older members what's typical for your chapter.
- School dances: a fun short dress for a semi-formal dance, or see homecoming for hoco.
- Weddings with a semi-formal dress code: a midi or knee-length dress. Skip white, and see wedding guest dresses.
- Daytime events: lighter fabrics and florals. Evening events: darker colors, satin and a bit of shine.
How renting a semi-formal dress works
- Find the dress. Filter by size and color. Each listing shows the owner's photos and rental prices.
- Message the owner about fit, length and anything you want to know.
- Pick your dates. Owners set a flat price for each rental length they offer (2, 4, 5, 7, 14 or 30 days). A 4- or 5-day rental is a safe default for a shipped dress.
- Wear it, then send it back with the prepaid label, or hand it back for a local rental.
Frequently asked questions
What should I wear to a semi-formal?
A knee-length or midi dress in a dressy fabric is the safest choice. A polished mini also works for a college semi-formal at night. Save floor-length gowns for formals and black tie.
Is semi-formal the same as cocktail attire?
Close. A cocktail dress always works for a semi-formal. Cocktail attire is often a little sharper and shorter, and semi-formal leaves room for midis and softer looks.
How much does it cost to rent a semi-formal dress?
Cocktail and semi-formal dresses on e.closet have a median rental price of $50 for the shortest length the owner offers. Delivery and a small service fee show at checkout.
