Where to Buy Rachel Allan Prom Dresses

"From size 00 to 30W," says the brand's prom page. No single gown covers that. Prom, homecoming, LBD and couture styles are cut 0 to 12, 0 to 16 or 0 to 20, depending on the style, so the core prom line stops at 20. Some shops list those runs from 00 rather than 0. The sizes past 20 come from Curves, which runs 14W to 24W or 14W to 30W and is designed to match the main collection, and from the bridal and quinceañera gowns. Budget a little extra if you wear a 14 or up. At one large prom retailer, about half the Rachel Allan styles cut past size 12 cost $40 more from 14 up, while the rest hold one price all the way to 20. Your shop's tags may differ, so ask. Prima Donna pageant styles run 0 to 12.

Formal sizes don't follow street sizes, so let the fitting room decide. Try the gown on at the shop and have the stylist size you. Caught between two sizes? The brand says to buy the bigger of the two. A seamstress can take a dress in. Letting one out is a different story.

Tall? Bring the shoes you plan to wear. The brand cuts its Prima Donna pageant gowns longer than its prom gowns, and a few minutes in the fitting room will tell you whether a style reaches the floor on you.

Rachel Allan is sold through retailers. Find one with the brand's store locator, then call ahead to ask which lines and sizes are on the floor.

Returns follow the shop you buy from, so get its terms first. No standard special-order time is published. Get an arrival date from the shop, in writing if you can, before any deposit changes hands.

The main line splits by season. Long prom gowns come out in spring, and short homecoming dresses follow in fall. At one large retailer, new prom styles have gone live from January through March, most of them in March, with the fall styles following in July. Want first pick? Start asking your shop in January, and leave room for alterations after that.

The general prom-season advice applies here. New Jersey's Division of Consumer Affairs, in a 2014 alert, told shoppers to buy from designer-authorized retailers and check that the brand lists the seller, to compare prices, to look for a physical address and phone number, and to pay by credit card. A 2016 report on Tulsa's KJRH, drawing on the brand-protection firm MarkMonitor, added two tells: prices "should be consistent across all authorized retailers," and "fraudulent sellers often misspell the brand name to trick customers."

Sales muddy the price test. Authorized shops do mark Rachel Allan down, so a discount alone proves nothing. A price far below every listed shop, from a seller that isn't on the store locator, is the real warning. Buying secondhand? Ask for the style number and the shop the dress came from, then look the style up at a listed retailer and compare the photos.

Florida leads our listings, followed by Texas, New Jersey, Alabama and Illinois. The Deep South is strong too, with Georgia and Mississippi close behind. A few stores stock an unusually wide spread of its lines:

There is no Rachel Allan. The federal trademark record for the name says it "does not identify a particular living individual." The label is a trade name of Party Time Formals Inc., an Illinois corporation. A 2017 deal announcement from its M&A adviser gives 1985 as the founding year; the brand's own site names no year.

In 2017 the company bought Mary's Bridal of Houston, which is now a sister label, and some retailers file Mary's bridal and quinceañera styles under Rachel Allan. That deal announcement placed the company in Burr Ridge, Illinois. Its trademark record, maintained with the US Patent and Trademark Office in 2025, lists Stafford, Texas, near Houston.

The brand calls its pageant collections "award winning" but names no awards. Its own site has claimed celebrity wearers, though. A 2015 version of that site said Carrie Underwood wore style 6814 for a CMA campaign and listed Vanna White in several styles. Those credits come from the brand alone, and we found no outside confirmation.

One prom moment came from close to home. In 2018, two high school students from Magnolia, Texas, north of Houston, staged their pre-prom photos at a Whataburger, and the shoot made national news. The brand's blog says the gown in those photos was Prima Donna style 5002, a royal blue pageant dress. The news stories did not name the maker.
