Dress Guide
Dresses, By the Details
Lined or not — it changes everything
Roughly a quarter of our dresses are lined, and the rest are not. Lining changes how a dress hangs, how opaque it is and what you need underneath it. Each page states which, so it is worth checking before a warm-weather or evening buy.
Length is measured, not guessed
Mini, midi and maxi mean different things between makers. The measured length per size is listed where the maker supplied it, which is the only reliable way to know where a hem will land on you.
Fabric sets the occasion
Polyester, cotton and rayon dominate the edit, and most styles are cut without stretch. The composition on each page is the quickest read on whether a dress is an everyday piece or an evening one.

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.
