The shop puts its own founding at 1987 and describes itself as an independent, woman-owned boutique that hand-picks pieces rather than stocking racks deep. That shapes what a prom shopper finds here. This corner of Santa Clara County has big-box formalwear a short drive away; Penelope is one suite, with European labels next to evening gowns, and Jovani, Alyce Paris and MNM Couture among the brands whose retailer locators list this address. Alterations and tailoring are handled in house, which is the practical reason people come back to a small store instead of ordering a gown to a doorstep.
The duplicate-dress question
A 2015 prom guide from SanJose.com reported one practice here worth asking about: the store notes the gown and the event it is going to, so a second buyer does not leave with the same dress for the same night. That was a decade ago and policies change, so confirm it on the phone at (408) 554-0054 before you count on it. If it still holds, it is the single most useful thing this shop offers a senior at a large high school.
Getting there and the two free hours
Penelope sits at the Stevens Creek Boulevard end of Santana Row, directly across Stevens Creek from Westfield Valley Fair, blocks from both I‑280 and I‑880. Parking is no longer free: San José Spotlight reported in August 2024 that Santana Row began charging after Valley Fair shoppers filled its garages, with the first two hours free, $2 an hour after that, and a $10 daily cap. A first round of try-ons and a conversation about hems fits inside two hours. A whole Saturday of shopping the Row does not, so budget for it.
One thing to sort out by phone: listings split between two addresses on the same block. Brand locators and the Santana Row directory give 377 Santana Row, Suite 1165, while the store’s Yelp and Facebook pages list 2960 Stevens Creek Blvd, Suite A — the two-story retail building next door. Ask which door to walk through. Those listings show a 10 a.m. to 6 p.m. day, seven days a week; still worth confirming, especially in March and April.
Who is within range
Del Mar High School shares the 95128 ZIP code with this address — 1,224 Del Mar Ave, about 1,350 students, part of the Campbell Union High School District. The rest of that district is a short drive out: Westmont in Campbell, plus Prospect, Leigh and Branham. Willow Glen and Lincoln pull from the neighborhoods east and south. Presentation and Archbishop Mitty add private-school seniors from the same few square miles. None of them are more than a normal cross-town trip, which means the shop’s clientele on any given spring weekend can easily include two girls from the same class.
The upside of this location is that nothing here is a long haul. Trudy’s Brides on South Bascom in Campbell is minutes away, and Valley Fair’s department stores are across the street. A shopper who does not find her dress at Penelope has other stops the same afternoon — and one who does can hand the gown straight to the in-house tailor instead of hunting for a seamstress in May.
