Before You Order
Every product page shows its own estimated delivery window, because some pieces are stocked in US warehouses and others ship from overseas. Shipping is free on every order and tracking is included.
Use the size guide link next to the size options. Where we hold a size table for that brand it opens right there, and the Fit & Measurements section lower down lists this exact piece's measurements whenever the maker publishes them.
Returns are open for 30 days on unworn items in their original packaging, for a refund or an exchange. The full terms are in our refund policy.
Roughly half our range is stocked in US warehouses and the rest ships from overseas. The delivery estimate on each product page tells you which one you are looking at.
Sometimes, and not on a schedule — our range comes from boutique labels in limited runs. New styles arrive weekly, so the New In collection is the best place to check.
