The Best Places to Buy Vintage — and Resell Your Old Clothes

Poshmark's business model is built on a marketplace structure, where the company itself never has its hands on any of the pieces that are bought or sold through their website. Much like eBay, the seller creates their own listing, price, and photographs, and works directly with the buyer when it is sold. The brand's point of difference, however, is that it's largely app-based. So, as a seller, your initial listing must be created on the app itself, not the website. While you can use the site to modify your closet and shop, Poshmark very clearly tries to drive all users to their mobile platform.
