Frequently asked questions
How fitted are sheath dresses?
A sheath is cut straight and close through the body without flaring. They read tailored rather than loose, so size with that in mind.
Are these dresses actually modest?
Yes. Every dress here is tagged with a modest neckline, and we exclude sheer, cut-out, open-back and mini styles by default.
Are all of these under $100?
Yes -- the list is filtered to an effective price (after any sale) below $100, so every one of the 452 pieces fits the budget.
How often is this collection updated?
It refreshes daily -- new arrivals are added and sold-out pieces drop off automatically, so what you see is in stock.
