Dressing for black tie.

Black tie is the most formal dress code most of us will meet: an evening event where a floor-length gown is the classic choice. Here is how to do it well.

The essentials

Floor length

A gown that reaches the floor is the safest choice. A very elegant, dressy cocktail dress can work at more relaxed black tie events.

Luxurious fabrics

Satin, silk, velvet, crepe and sequins all read as formal.

Polished finishing touches

Heels or elegant flats, a small clutch, and jewelry chosen to match the neckline.

Three ways to wear it

Classic

  • Black or navy column gown
  • Pointed heels
  • Diamond-look studs

Modern

  • Satin bias-cut gown in a jewel tone
  • Strappy sandals
  • Metallic clutch

Winter formal

  • Velvet long-sleeve gown
  • Closed-toe heels
  • Elegant evening coat

Black tie optional

"Black tie optional" means the hosts will be in formal wear but guests have some flexibility. A floor-length gown is still perfect; a dressy cocktail dress, an elegant midi or a sleek tuxedo-style suit also fit.

Frequently asked questions

Can I wear a short dress to a black tie event?

Floor length is traditional. At relaxed black tie events a very formal cocktail dress can work, but when in doubt, go long.

Can women wear trousers to black tie?

Yes — a well-tailored tuxedo suit or a sleek, wide-leg evening jumpsuit in a luxurious fabric is formal enough.
