“What do festive, cocktail, semi-formal and dressy casual mean on an invitation?”
Dress codes explained: festive, cocktail, semi-formal and dressy casual
Short answer
Dress codes run from casual to black tie. Dressy casual is polished separates or a simple dress, semi-formal is a knee or midi dress or elegant separates, and cocktail is a bit more festive and evening-leaning. Festive means dress up with color, sparkle or a holiday touch. Guides disagree on whether cocktail or semi-formal is dressier, so when the invitation is unclear, ask the host.

Dress codes from least to most formal, as described by Emily Post and wedding guides (checked October 17, 2026)
| Dress code | What it means | Typical outfit |
|---|---|---|
| Dressy casual | Polished, one step above everyday wear | Nice separates or a simple dress |
| Semi-formal | More formal than office wear, slightly less than formal; leans dressier for an evening start | Knee or midi dress, dressy jumpsuit, elegant separates |
| Cocktail | A bit more festive and evening-leaning than semi-formal | Knee-length or midi dress in satin or another evening fabric |
| Festive | Dress up with color, sparkle or a holiday touch | Velvet, sequins or jewel tones |
| Black tie | The most formal code on a wedding invitation | Floor-length gown, or the dressiest cocktail dress |
The short answer
Think of a dial from casual to black tie. Dressy casual sits near the casual end. Semi-formal and cocktail sit in the middle, and black tie is the top. Festive is a different kind of instruction: it does not say how long or formal the dress is, it says to add color, shine or a seasonal touch.
The table above gives a one-line version of each. The sections below explain where people get stuck.
Semi-formal and cocktail
Emily Post describes semi-formal as more formal than office wear and slightly less formal than formal. It is the most common wedding code, and an evening start means leaning dressier. See the semi-formal wedding guest guide.
Cocktail sits between semi-formal and formal. A knee-length or midi dress in satin or another evening fabric passes, and so does a dressy jumpsuit. See the cocktail guide.
Where guides disagree
Guides disagree on which of the two is dressier. The difference is small in practice: a midi dress in a dressy fabric works for either.
When the invitation says one of the two and the venue is a hotel ballroom or the event starts in the evening, go with the dressier choice. Overdressing a little is easier to live with than underdressing.
Festive and holiday dress codes
Festive usually appears on holiday party invitations. It asks for color, sparkle or a seasonal touch, for example velvet, sequins or jewel tones. Emily Post uses the words creative or festive black tie for a formal event that adds color and embellishment.
For ideas, see the holiday party dress guide.
What to ask the host
If the code is unclear, ask one question: what is the venue, and what time does it start? An answer like "a restaurant at 7" points toward cocktail or semi-formal. "A backyard at 2" points toward dressy casual.
You can also ask what other guests are wearing. Hosts usually answer in a sentence.
Fabrics and shoes by level
Dressy casual allows cotton, knits and block-heel shoes or polished flats. Semi-formal moves to crepe, satin and heeled sandals or pumps. Cocktail and festive add satin, velvet and sequins. Black tie adds floor-length hems and dressy heels. Fabric usually reads dressier than length.
