Go to the wrong door and you will be looking at wedding gowns. Blossoms has two separate shops on the upper level of Stoneridge Shopping Center in Pleasanton. The bridal and formal store — wedding dresses, mother-of-the-bride, evening — sits next to the DMV field office. Blossoms Prom is a different storefront farther along the same second-floor hallway, and that is where the prom and quinceañera gowns are. Both are appointment only. You book through the store, not by walking in.
Prom is not something this business added on the side. It opened in 2003 as a prom dress store in Valley Fair Mall down in San Jose, and the bridal side came later, after the evening and social-occasion inventory grew. The Pleasanton location is where all of it now sits.
The brands we can confirm
Jovani, Jessica Angel, and Jasz all list this store as an authorized stockist on their own retailer locators. That is a specific corner of the prom market: fitted, heavily beaded, high-shine gowns, the ones that photograph the way girls expect them to. Blossoms also special orders and custom tailors to measurement, and keeps an off-the-rack selection for shoppers who need a dress in hand now rather than in eight weeks. Alterations are done in-house by their own tailors, which matters more than it sounds — a fitted Jovani almost always needs work, and sending it out adds a week and a second appointment somewhere else.
Finding the door
Stoneridge is a big mall with a parking problem of the boring kind: too much of it, spread too wide, and the wrong lot means a long indoor walk. The store’s own directions say to park in lot E17, at the mall entrance between JCPenney and Men’s Wearhouse, because that entrance puts you straight onto the second floor. Note that JCPenney closed at the end of February 2026, so the anchor name on those directions is gone even though the entrance and the lot number are not. After Sears left in 2018 and Nordstrom in 2020, Macy’s is the last department-store anchor in the building.
If nobody in the house wants to drive, the West Dublin/Pleasanton BART station is about a five-minute walk from the mall, which makes this one of the few prom shops in the East Bay a sophomore can reach without a ride.
Who shops here
Two of the larger high schools in California’s Tri-Valley are a few miles from this parking lot. Amador Valley, the Dons, enrolled 2,583 students in 2024–25; Foothill, the Falcons, enrolled 2,208. They are cross-town rivals in the same district, which means two separate dance dates and two separate crowds looking for gowns nobody else will have. Amador plays in the East Bay Athletic League alongside San Ramon Valley and Granada, so the wider circle of schools that ends up in this store on a Saturday in March stretches from Livermore to Danville.
Shoppers who review this store use “senior ball” as often as “prom,” which is standard around here and worth knowing if you moved in from somewhere else.
Before you go
- Closed Tuesdays and Wednesdays. Saturday is the default appointment day, so book ahead of the March rush.
- Appointment only at both storefronts. Confirm which one you want when you book — prom and bridal are not the same address inside the mall.
- The DMV office is the landmark for the bridal store. If you can see the DMV line, you have gone past the prom shop.
- Quinceañera gowns are in the prom storefront, not the bridal one.
