Four days a week, this is an appointment shop. DuPage County has plenty of stores you can wander into on a whim; this is not one of them. The boutique’s own site sets the schedule out directly: Tuesday through Friday by appointment, Saturday 11 to 5 with no appointment needed, closed Sunday and Monday. For a family coming from Bensenville, Villa Park or Bloomingdale, that is the first thing worth knowing. A Wednesday afternoon drop-in is a wasted trip. A Saturday in the thick of season means sharing the floor.
The trade-off is what the appointment buys. The shop is small, family-run and woman-owned, in business since the late 1980s by its own account, and the owner of record is Carmela Capriati. Customers writing on the store’s own testimonial page name the staff and the seamstresses individually, which is a fair signal of how a fitting there tends to go.
Brands and what else is in stock
Three prom labels list this address on their official retailer locators: Alyce Paris, Dave & Johnny and Terani. Prom is not the whole business. The store describes its specialties as mother of the bride and groom first, then prom, homecoming, quinceañera, sweet sixteen, military ball and other special occasion dresses, plus casual wear. Accessories are jewelry and belts. It does not carry shoes, so plan on sourcing those elsewhere before a final fitting.
The schools nearby
Addison Trail High School sits a little over a mile away at 213 N. Lombard Road, with roughly 1,900 students in grades 9 through 12. It is one of the two schools in DuPage High School District 88, paired with Willowbrook in Villa Park, so a Blazer and a Warrior can end up in the same shop on the same Saturday. Fenton, in Bensenville, is the other close-in public high school, with about 1,400 students. None of the three is far enough away to make Lake Street an inconvenient stop.
Two formal seasons, not one
Addison is a village of about 35,500 people where, by the Chicago Metropolitan Agency for Planning’s 2023 community snapshot, Hispanic or Latino residents are the largest group at 15,524 — narrowly ahead of non-Hispanic white residents. A shop here that stocks quinceañera gowns alongside prom is answering its own trade area rather than adding a sideline, and the store lists both without ranking one behind the other. Lake Street is not short of options either: Scelebrations, a quinceañera specialist, is at 56 W. Lake, which makes it possible to see two very different shops in one afternoon without moving the car far.
The block itself
W. Lake Street is U.S. Route 20 through Addison, and U.S. 20 meets I-355 here, which is how most out-of-town families will arrive. Number 514 puts the boutique directly beside 510 W. Lake, the Angelo Caputo’s Fresh Markets store, with Brookhaven Marketplace a few doors west at 648. Listings for the store note a private lot and wheelchair access. One practical note for anyone searching or calling: the business turns up as Mona Lisa Boutique, MonaLisa Boutique and Mona Lisa’s Boutique depending on the source. All the same shop, all the same phone number.
