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, and we exclude sheer, cut-out, open-back and mini styles by default.
Are all of these under $150?
Yes -- the list is filtered to an effective price (after any sale) below $150, so every one of the 51 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.
