27 autumn wedding guest dresses to shop now if you're getting ahead of the next season

Though it's still very much summer, the hunt for the best autumn wedding guest dresses is well and truly underway. There's no such thing as "wedding season" this year – instead, we've (wonderfully) got an entire year of the romantic celebrations ahead of us, and it's never to early to start preparing. So, as we see the first swathes of A/W trends begin to line our fave high-street shops, we're putting our summer wedding guest dresses on hold 'til next May and shopping autumn wedding guest dresses, instead.

The shopping part is easier said than done, however. Whether you're after autumn wedding guest dresses with sleeves, something sparkly for a magical indoor affair or a mini dress adorned in autumnal florals, it can be hard to strike the balance between “best dressed”, “out-shining the bride” and “overly practical”. You'll want to stay warm while posing for pics outside in the autumnal breeze, granted, but it's not exactly going to be freezing either - especially when you're on the dance floor - so how to strike the perfect balance?

Our coffee tables are still chock-a-block with wedding invites, so we've been searching high and low for the perfect wedding guest outfit to don at them all. After much deliberation and a few trend-related chats with GLAMOUR's favourite dress brands, we've bookmarked 27 gorgeous autumn wedding guest dresses that are sure to have you feeling your very best. From online clothing stores like ASOS, Oasis, influencer-adored Warehouse, Rixo and Self-Portrait, we've got a stunning array of Instagram-ready gowns that will pop on your feed - and IRL. Expecting? Head this way for some gorgeous maternity wedding guest dresses that'll suit your growing figure. We've also found wedding guest jumpsuits, if a dress isn't really your thing.
