Wedding season is officially upon us. With a calendar full of RSVPs, the pressure to buy something new for every single dress code is real.
Instead of draining your bank account on an outfit you’ll only wear once, ThredUp is opening a first-of-its-kind secondhand boutique experience designed entirely for wedding guests.
Step inside The Guest List pop-up
For one day only, you can head down to 21Greene in SoHo to shop a beautifully curated edit of secondhand occasionwear. Dresses start at just $20, and you can score discounts of up to 50% off.
ThredUp is finally giving guests the special treatment usually reserved for brides. If you are ever confused by an invitation, you can use their new Dress Code Decoder. This clever styling tool translates vague wedding dress codes into curated, shoppable secondhand looks.

Free dresses, custom bouquets, and From Lucie cakes
You will definitely want to arrive early for this one. The first 100 attendees will receive a completely free dress from ThredUp.
While you browse the racks, you can stop by the build-your-own bouquet bar to create a custom floral arrangement. If you have a sweet tooth, they are also giving away 200 complimentary mini cakes from the cult-favorite bakery From Lucie to the early arrivals.
Trade in your old dresses for credit
Have a gorgeous guest dress just sitting in the back of your closet? Bring it with you!
The pop-up features a dress trade-in designed to keep special-occasion pieces in circulation. If you bring a pre-loved dress, you will score an additional $15 ThredUp credit toward a future purchase. Just make sure it is in good condition—something you would feel comfortable giving to a friend.
Everything you need to know before you go
This is a stylish, sustainable alternative to fast fashion, helping you find a one-of-a-kind look you will actually want to wear again.
