33 Chicest Autumn Wedding Guest Dresses of 2025

As a bride, there’s nothing more important than setting the date for when you’ll walk down the aisle. But as a wedding guest, where this day falls on the calendar can dictate so much of what you can wear. Such is the case for autumn wedding guest dresses.

Where summer temperatures revel in flirty cuts, vibrant hues and whimsical patterns, autumn weddings will often have us hiding our gowns under a structured trench coat, woollen duffle or tuxedo jackets we nicked from someone else. (Lest we go jumper-free and risk freezing in the cold!)

Autumn may feel like quite a restrictive season to style for, especially given the unpredictable weather, perpetual grey skies and cold evenings that come with it in the long stretch towards winter. But I think it’s an opportunity—this in-between climate can actually serve as a source of inspiration. I often find that the wedding guest outfit options for autumn can be chicer than their warm weather counterparts and offer more variety in terms of colour palette, print and silhouette.
