If “Black Tie Optional” doesn’t immediately give you outfit inspiration, don’t worry; it’s way less complicated than it sounds. When a couple chooses to have a Black Tie Optional wedding, it usually means that the couple and their wedding party will be wearing Black Tie fashion: tuxedos and evening gowns.

The “optional” part can trip people up–just a quick Reddit search yields lots of guests looking for guidance. As one user put it, “What the heck is black tie OPTIONAL? Like you can wear anything from casual to fancy?” To clarify, optional means guests can choose to dress in Black Tie attire, or wear something slightly less formal, like a regular suit or a cocktail dress. Because the wedding party will be extra formal, it’s polite to dress as formally as you feel comfortable doing at a Black Tie Optional event.

The Black Tie Optional wedding dress code for women can feel a little tricky at times, so here are some helpful hints for mastering this formal dress code!

  • Wear a full-length or mid-length dress. Short dresses won’t match the formal vibes, but formal cocktail dresses are ok.
  • Wear dark or rich hues like black, gray, navy, or jewel tones if you’re unsure of an appropriate color palette.
  • When in doubt, stick to solid colors, since patterns can sometimes feel too casual for a formal dress code.
  • Aim for formal footwear. Think heels, closed-toe wedges, or fancy, embellished flats.
