36 wedding guest dresses for your next open bar — Er, celebration of love

Because looking incredible is the least you can do

By and

There are so many wedding guest dresses out there, but whether it's an intimate gathering of nearest and dearest or a 300-person soirée, figuring out what to wear to a ceremony or reception is much trickier than it sounds. You want to feel comfortable but chic, fabulous but free — and you defo don't want to look like you're wearing a funeral dress or trying to upstage the bride in an ivory hue.

Shop our fave wedding guest dresses



And assuming you don't fancy re-wearing a fancy summer dress or borrowing from a friend, the next best thing you can do is invest in something you'll wear again and again. I'm a proud outfit repeater, so a wedding guest dress that looks just as good with ballet flats as it does with strappy heels or trainers is a serious win.

Below, Cosmo's Shopping Editor Kara Kia rounds up 36 of the best dresses to wear to a wedding in 2026 — with a gorgeous pick across every price point. If you're unsure about dress codes – like Black Tie or Cocktail Attire – our guide on what to wear to a wedding as a guest breaks down the style rules for every destination, venue, and location.
