WhatchamaCallit Boutique

WhatchamaCallit runs its Far North Dallas prom floor without a booking calendar. There is no appointment to book at the Preston Road showroom, no reservation fee and no fifteen-minute slot to protect. You show up on a Saturday with your mom and two friends, and a stylist meets you on the floor.

That policy only works because of the size of the place. The company's website makes three claims: it is the biggest prom dress seller in Texas and across the Southwest, it keeps more than 20,000 dresses in stock, and it moves more Sherri Hill and Jovani than any other store in Texas. Over the years the Dallas showroom has become the first stop for north Dallas and Collin County families who would rather see everything in one building than chase a single style across town.

Spring weekends here are loud, busy and full of mirrors, by design.

How to shop a floor this big

Twenty thousand dresses sounds like a problem until you have done it once. The Dallas showroom page promises shoppers "the freedom to browse through our showroom which features thousands of gorgeous gowns and dresses from many of the finest designers around the world," and browsing is the point. A little planning makes the afternoon go faster:

• Know your silhouette before you know your designer. The floor runs deepest in Sherri Hill and Jovani, and the store's designer list also includes Amarra, Portia and Scarlett, Alyce Paris, La Femme, Primavera Couture, Tarik Ediz, Ashley Lauren, Jasz Couture and Jessica Angel. Most of them cut mermaids, ballgowns and two-pieces, so the shape narrows things faster than the label does.
• Check sizes online first. The website's prom filters run from 000 up through 32, plus women's sizing, and there is a separate Curvy Corner collection. If you wear something outside the middle of the size chart, you can see what exists before the trip.
• Look at prices before you leave the house. Every style on the site carries a posted price, which lets you walk in with a number instead of guessing.
• Go early in the season. The prom page warns that "popular sizes and colors sell quickly," and that warning applies most to the Sherri Hill styles everyone saw on Instagram the same week you did.
• Bring a short list, not a long one. A saved wishlist on the website is an easy way to arrive with five style numbers instead of fifty screenshots.

That last point echoes what store manager Alexa Graham told D Magazine back in 2021.

Five years later, her advice still holds.

The appointment question comes up so often that the store answers it on its own blog. Its 2026 designer roundup ends with the house rule:

We only take walk-ins, so come visit us whenever you're ready to start your prom journey.

Hillcrest, Pearce and Plano West shoppers on Preston Road

The showroom sits on Preston Road in Far North Dallas, up near Belt Line, where the city's north end runs into Addison, Richardson and the south edge of Plano. A long list of big high schools surrounds that corner. Dallas ISD students from Hillcrest and W.T. White come up Preston or the tollway. Richardson's Pearce High School lies to the east. Plano West Senior High and Carrollton's Newman Smith are both close enough for a weeknight visit, and Frisco is a straight run down the tollway. For anyone comparing prom shops across north Texas, this is the one with the deepest single inventory to compare against.

Prom drives the spring, but the floor turns over through the year.

• Homecoming

  Short-dress racks fill in late summer for the fall dances

• Pageant and evening

  Collections the site carries, as it does cocktail dresses and a mother-of-the-bride section

• White Collection

  For brides and anyone else who needs a white dress

• Jim Ball Designs

  Jewelry alongside the gowns, for anyone matching earrings to a gown

Families on the Tarrant County side have a closer option. The company's Fort Worth showroom on West Freeway carries the same designers, keeps the same walk-in policy for prom and runs the same weekly hours, so the choice usually comes down to which side of the metroplex you live on.
