Amy started it. Her daughter Victoria grew it. Mimi’s Prom is a family-owned, woman-led business, and the mother-daughter pair now run four prom stores: Overland Park on the Kansas City side, Denver, the original shop in Sullivan, and this one on Clayton Road in Chesterfield. Across those four, the company says it carries the largest selection of prom dresses in the Midwest and the Rocky Mountain region, and its buyers travel the country to pick every dress that ends up on a rack.
Nearby schools include Parkway Central and Marquette in Chesterfield, Parkway West in Ballwin, Lafayette in Wildwood and Ladue Horton Watkins.
The company knows what it wants a visit to feel like. It describes Mimi’s as a place where memories get made with family and friends, where confidence gets built and individuality gets celebrated, and it invites girls who travel from near and far to #BeAMimisGirl. The managers and stylists at each store are described as highly trained, and the goal is a personal appointment rather than a self-serve browse. Prom is the whole point of the store, and the stock is chosen for juniors and seniors in spring, then for underclassmen and seniors alike when homecoming comes around in the fall.
What the Chesterfield racks hold
The St. Louis store states its numbers for both seasons.
Long prom dresses, sizes 00 to 24
$275Average $400 to $500Over $1,000
Short homecoming dresses run from $75 to $1,000, with a typical price near $300, in the same 00 to 24 run as the long styles.
The designer list leans hard into prom specialists: Sherri Hill, Jovani and its JVN line, Ellie Wilde, Ashley Lauren, Ava Presley, Faviana, Atria and 2Cute Prom. Stock turns daily as dresses sell and new ones arrive.

The appointment system, and why it exists
Every visit at Mimi’s is booked ahead, so nobody spends the afternoon waiting for a fitting room. The store explains it this way.
All Mimi's locations are open by appointment only. Your experience begins when you arrive for your appointment time - appointments alleviate long wait times to get in & for a fitting room to open up.
Each booking comes with a stylist. The staff also shares a helpful scheduling tip: weekends here are full of shoppers, guests and stylists at once, a scene the store cheerfully calls organized chaos. A weekday slot is the calmer option.
A few tips help the try-on go smoothly, starting with what goes on under the gown.
Wear
- Light-colored underwear
- A strapless or sticky bra
- Any shapewear you plan to use
Leave in the car
- Outside food and drinks
Settle on a price ceiling at home, since the store suggests choosing a range before you book.
Good to know: all sales are final at every Mimi’s location, including special orders, layaway and sale dresses.
For a family that needs time to pay, the chain offers free layaway for 60 days at all four stores, and it takes cash and the major cards, though not checks. Alterations are handled outside the shop. Mimi’s keeps a list of seamstresses that customers have recommended, and the Chesterfield staff will text that list to anyone who bought a dress there.
The Sullivan store, out along I-44 in Franklin County, is part of the same family business and runs its own prom floor alongside bridal; our page on Mimi’s Bridal in Sullivan covers that location. For other options around eastern Missouri, this site lists shops from St. Charles County to Jefferson County.
What Chesterfield shoppers ask Mimi’s Prom StL
Can I tip my stylist at Mimi’s?
Yes. The store notes that gratuity for your stylist is welcome but optional.
Is a weekday or weekend appointment better in Chesterfield?
The store itself points shoppers toward weekdays for a quieter visit. Saturdays bring more shoppers, more guests and more energy on the floor.
