Cocktail attire is a semi-formal dress code for events like cocktail parties, weddings, and upscale evening gatherings, sitting between business casual and black tie.

What to wear

[3][7][1]
MenWomen
Dark suit, dress shirt, tie, and polished leather shoes. Knee-length or midi dress, a chic suit, jumpsuit, or elegant separates with polished accessories.

Easy rule of thumb

Choose something tailored, refined, and more elevated than everyday wear, but not as formal as black tie.

Good examples

  • Men: navy or charcoal suit, white shirt, tie, and dress shoes.
  • Women: silk, chiffon, or satin dress with heels and simple jewelry.
  • If the event feels more formal, lean darker and more tailored; if it feels modern or creative, tasteful color and stylish accessories can work.

TL;DR

Cocktail attire means polished, dressy, and event-appropriate, but not full formalwear.
