Your Guide to Dressing for a Formal Black-Tie Summer Wedding

When you hear black-tie wedding and summer in the same sentence, it can feel a little confusing.

Are you supposed to go full glam? Is satin too hot? Can you wear something breezy without looking too casual? Here’s the truth: you absolutely can look stunning, stay cool, and follow the dress code—all at once.

For a summer black-tie wedding, think long gowns with structure, lightweight fabrics with movement, and rich tones that elevate the moment.

Skip anything too short, too casual, or overly sheer. This is your chance to dress up, so lean into elegance—but do it with comfort in mind.

Flowy chiffon, draped satin, mesh paneling, and bold cuts can all work beautifully when styled with intention.
