Rentals

Renting a dress makes sense—for your budget, your closet, and the planet. It’s a way to wear something incredible without the pressure to own it forever. Whether it’s for a night out or a big event, renting gives you access to pieces you might not normally splurge on, and keeps fashion in rotation instead of in the landfill. While there are other options, we chose Rent the Runway for our rental selections due to it’s accessibility for most people. (as opposed to peer-to-peer rentals that are NYC based)

One caveat to rentals: reserve in advance or the style you want may not be available.
