Pickle is a rental marketplace. We seek to make fashion more affordable, sustainable, and accessible by enabling people to rent clothes directly from one another right in their city. Our unique peer-to-peer model allows Pickle to have the most in-demand fashion out there. And our same-day local courier delivery not only allows our users to find a last minute outfit when they’re “in a Pickle”, but also helps people get access to items at ~80% off the original retail!
