Frequently asked questions
How fitted are these mermaid styles?
Mermaid and trumpet cuts stay close through the hips and flare below the knee. They are the most fitted silhouette we tag, so check the retailer's size guide.
Are these dresses actually modest?
Yes. Every dress here is tagged with a modest neckline, long sleeves, and we exclude sheer, cut-out, open-back and mini styles by default.
How much do these cost?
Prices start around $64 and run up from there; each card shows the live price and links straight to the retailer.
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.
