Wedding season is upon us, so we’ve compiled a list of more sustainable wedding guest outfits from top-rated brands.

More sustainable wedding guest outfits inspiration

Weddings can be stressful—for the couple, their families, and yes, sometimes even their guests. For the latter, it’s often about deciding what to wear and the pressure to invest in a new outfit for the occasion. And while it might seem tricky to find something you can wear beyond the one-day celebration, we’re here to help. 

First, we recommend checking what’s already in your wardrobe—try restyling an outfit you’ve already worn, or pairing items that you’ve never worn together before to create a new outfit combo. If that doesn’t work then it’s time to explore secondhand options. Outfit rental is also an increasingly popular solution for event dressing. Some of our favourite platforms are Rent the Runway, Hurr, By Rotation, Vow to be Chic, Glam Corner, and MyWardrobe.

And if you need to buy something new, scroll on for our list of top-rated brands that’ll help you dress to the nines in more sustainable wedding guest attire—whether it’s a clutch bag, gown, suit, or accessory.

Buying occasionwear can get expensive, and while more sustainable clothes do cost more than the ultra low prices we’re used to fast fashion serving up, there is still a spectrum. In this round-up, we’ve included some more affordable brands, such as OMNES, SeamsFriendly, and Ninety Percent, for those shopping on a smaller budget.
