What to Wear to a Summer Wedding: A Guest Outfit Guide

A summer wedding is a joy to dress for — until the heat, a strict dress code and hours of photos collide. The goal is simple: look elegant, stay cool, and feel comfortable from ceremony to last dance. Here's exactly what to wear to a summer wedding as a guest, decoded by dress code and venue.

Decode the dress code first

• Black tie / formal: a floor-length or elegant midi dress in a light, luxe fabric; a linen or lightweight suit for men.
• Cocktail: a knee-to-midi dress or a smart jumpsuit; a summer-weight suit.
• Semi-formal / garden party: a floral or pastel dress; chinos with a crisp shirt.
• Beach / destination: a floaty maxi and flat sandals; linen shirt and trousers.

Fabrics that keep you cool

In the heat, fabric is everything:

• Linen, cotton and chiffon — breathable and light.
• Floaty, loose silhouettes that let air move.
• Avoid heavy synthetics that trap heat and show sweat.

A well-chosen versatile dress in a breathable fabric is the easiest win — in summer, swap the classic black for a lighter colour.

Dress for the venue underfoot

• Garden or beach: block heels, wedges or elegant flats — stilettos sink into grass and sand.
• Indoor or air-conditioned: heels are fine; bring a light wrap for cool rooms.
• Always pack: sunscreen, a hand fan, and flats for dancing.
