Information Architecture — Poshmark

Overview

Poshmark is a social commerce marketplace for new and secondhand fashion, home, and beauty. Its differentiator is the social selling model — Posh Parties (themed live shopping events), sharing listings to boost visibility, bundles for multi-item purchases, and an offer/counter-offer negotiation system. The IA treats every user as both a buyer and a seller, with the closet (profile) as the storefront and sharing as the primary growth mechanic.

Key pattern: "Share" is a primary action — sharing your own or others' listings to followers and parties is how items get visibility. The feed is a social timeline of shared listings.
