23 Unusual Dresses for Wedding Guests

Make your mark at any special occasion with the best unusual dresses for wedding guests who want outfits that are as unique as they are elegant

Whoever came up with "twinning is winning" had clearly never turned up to a wedding in the same outfit as another guest. To help you avoid this less-than-ideal scenario, we're bringing you our favourite unusual dresses for wedding guests, hot off the high street for 2020.

While there's nothing wrong with choosing a classic look, we are partial to quirky wedding guest dresses that show off your unique personality. Remember, unusual doesn't mean inappropriate - we're not talking Met Gala levels of sartorial extravagance. Our edit has everything from pared-back and elegant wedding guest dresses to stunning occasion outfits with bright and bold prints, alongside on-trend elements such as statement sleeves and colour blocking.

And because we know how important it is to make weddings more sustainable - including for guests - we've deliberately selected wear-again styles that'll see you through many a future social outing. As always, we’ve also got your budget in mind, and have included dresses with a purse-friendly price tag that definitely don't look cheap, as well as a designer pick or two for those looking to splash out. However much you’re looking to spend, you’ll feel like a fashion leader in one of these fabulous dresses. Happy shopping!

NB: We have included third party products to help you navigate and enjoy life’s biggest moments. Purchases made through links on this page may earn us a commission.
