Prom dress websites you can trust
Buying a prom dress online is safe when you buy from the right store. These boutiques sell real designer gowns, and they have for years.
How we chose these stores
Top Prom Websites started in 2012 as a watchdog for knock-off prom dress sites. Back then we also kept an approved list of online retailers. Getting on it meant we checked the store with the designers it carried and confirmed it had a real physical address.
Every store below was on that approved list. Each one is still listed in this guide, and each was running an online shop with a working checkout when we checked in October 2026. They are also real boutiques, so you can walk in and try a dress on before prom if you live nearby.
One honest caveat. That old check was about the store, not about every label on its website today. Before you buy a specific designer, confirm the store on that designer's own store locator. It takes about thirty seconds.

Shopping by designer? Start with the label
The surest way to buy a real Sherri Hill, Jovani or La Femme dress online is to start from the designer, not from a search result. Our prom dress designer pages list the stores that carry each label, and many of those are cross-checked against the designers' own retailer locators.
Red flags on any prom dress website
- A current designer style at half the price every other store charges.
- No street address anywhere on the site.
- Dozens of designers' dresses, all at the same discount.
- The store does not appear on the designer's store locator.
- Shipping from overseas for a label that is based in the United States.

Online or in person?
Prom dress sizing varies from label to label, and alterations take weeks in the spring. If you can get to a boutique, trying a dress on usually saves a return. Find a prom dress shop in your state and see what is close.
