Wedding Guest Guide: What to Wear When the Invite Says Black Tie Optional

As a guest at a wedding, you want to dress your best to celebrate the day, but you also want to choose an outfit that is appropriate for the occasion. Some weddings are casual while others are more formal, and there’s nothing worse than showing up to an event feeling either over- or underdressed.

So, what are you supposed to do when you get invited to a “Black Tie Optional” wedding? Don’t stress! Ahead, you’ll get the inside scoop on this dress code, and suggestions for gorgeous dresses to wear to the next black tie optional wedding on your calendar.
What Does Black Tie Optional Mean?

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 is for the benefit of the guests, who 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.
Styling Black Tie Optional Wedding Guest Dresses

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.
- Wear dark or rich hues like black, gray, navy, or jewel tones.
- 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 sophisticated flats.
