What does black tie mean for women?

The black tie dress code for women means a floor length evening gown. Black tie is the most formal dress code most people will meet, and it sits fifth on the usual scale: casual, smart casual, cocktail, formal, black tie, white tie. It is an evening dress code, used for weddings, balls, galas and awards nights.

Black tie does not mean wearing black. Any colour suits, in a fabric with weight or shine: satin, crepe, velvet, silk or chiffon.

What to wear to a black tie event

Black tie wedding. A black tie wedding guest dress is a floor length gown in any colour except white or ivory. Choose one you can sit, walk and dance in for a long evening.

Ball or gala. A ball or gala is the place for the most dramatic dress you own. A column gown, a mermaid shape or a full ball gown all fit.

Awards night or charity dinner. A simpler floor length dress suits a seated dinner. A satin maxi dress or a column dress in crepe is formal enough and comfortable at a table.

What does black tie optional mean?

Black tie optional means black tie is welcome but not required. For women, a floor length gown still fits, and so does a formal midi or tea length dress, or a dressy cocktail dress in an evening fabric. A very short dress does not. Black tie optional can be read as the formal dress code.

What not to wear to a black tie event

In most cases, avoid:

  • A mini or knee length dress
  • Casual fabrics, including cotton and linen maxi dresses
  • Daytime prints and sundresses
  • White or ivory at a wedding
  • Casual shoes or bags

A long hem alone does not make a dress black tie. The fabric has to be an evening fabric.
