How to Dress for a Black-Tie Summer Wedding (Plus-size Edition)

Black-tie doesn’t mean boring—and it definitely doesn’t mean uncomfortable. The key to nailing the dress code as a plus-size guest is choosing a gown that brings elegance and ease.

For summer weddings, go for lightweight fabrics that flow, breathe, and move with you—from dreamy chiffons to liquid satins and soft velvet blends.

Focus on structure in the bodice to give you support, while letting the skirt drape naturally for a graceful look. Don’t be afraid of color—deep jewel tones, soft pastels, and metallics can all feel just as formal as black.

And details matter: a well-placed slit, a flattering neckline, or a cinched waist can elevate your whole look.

Accessories should add sparkle without overwhelming—statement earrings, metallic clutches, and strappy heels are your best friends.
