Yvonne Lafleur opened this shop on Hampson Street on October 15, 1969, when she was twenty-two and just out of LSU. It was called You Boutique then, and the specialty was custom-fitted women’s blue jeans at $8 a pair. The store never moved. What changed was the merchandise: as her first customers married, she added wedding dresses and bridesmaids’ gowns, then lingerie and gowns for debutante and Mardi Gras balls, then a millinery department after she inherited an aunt’s hat blocks.
That order of events explains what a prom shopper walks into. This is not a warehouse of prom dresses. It is a full-line boutique in Louisiana’s oldest continuously owned ladies’ apparel business, with bridal, evening wear, sportswear, furs, custom hats and Lafleur’s own fragrance sharing the floor. The store’s tourism-board listing describes it as a 10,000-square-foot space; Lafleur herself calls it a big closet. Prom gowns here come from Terani, Tarik Ediz and Jessica Angel, and they sit in a room that also holds one-of-a-kind gowns from her own YLF label, which she and her daughter Stella buy in New York four times a year.
Alterations are included
The single most concrete reason to drive here instead of somewhere else: alterations are done on site by the store’s own seamstresses at no charge. Lafleur has said plainly that a serious store should hand a customer a garment already fitted — “A fine store should give it to you fitted properly” — and that includes hemming, taking in, steaming and bustling. For a gown that needs a hem and a bodice taken in twice before April, that is the difference between a sticker price and a real price. Ask what the timeline is when you buy, not after.
The Carnival calendar comes first
In most of the country a teenager needs one formal dress a year. In New Orleans the season starts at Twelfth Night in early January, when krewe balls begin, and runs to Fat Tuesday, with courts made up of that year’s debutantes. Prom is the second event, not the first. Lafleur has been stocking gowns for that stretch of the calendar since long before the store carried prom labels, and if you are shopping for a Carnival ball and a prom in the same spring, this is a store where both requests are routine. Louisiana proms also land earlier than Northern ones; the Willow School’s 2026 prom was ticketed for April 18.
Getting there, and who shops here
Hampson Street runs a block off South Carrollton in the Riverbend, the elbow of Uptown where St. Charles Avenue turns toward the levee. The St. Charles streetcar stops at the corner — the store cites Stop #299 — and Camellia Grill is around the block, with Carrollton Market and Refuel Cafe on the same short block of Hampson. Parking is street parking, and it is a narrow, busy few blocks; the streetcar is a legitimate option if you are coming from anywhere along the avenue.
The nearest high schools are all within a few minutes. St. Mary’s Dominican is under two miles away on Walmsley Avenue; the Academy of the Sacred Heart is up St. Charles; Isidore Newman and the Willow School are both Uptown, and Metairie Park Country Day is a short drive across the parish line. Tulane and Loyola sit between the store and Sacred Heart, so sorority formal traffic overlaps with prom season on the same racks.
If you want a large single-purpose prom floor with hundreds of gowns in one room, Pearl’s Place on Severn Avenue in Metairie is the metro area’s big-volume option and roughly a fifteen-minute drive. Yvonne La Fleur is the opposite kind of trip: a smaller, curated selection, staff who wait on you, and fitting handled in the building. Listed hours are 10 a.m. to 6 p.m. Monday through Saturday, closed Sunday. Call (504) 866-9666 before driving in, particularly in Carnival season.
One footnote worth knowing before you walk in: Lafleur, now in her late seventies, became an unlikely internet figure after a marketing hire began filming her explaining hats, gloves and perfume in the shop. The accounts have drawn well over a million followers combined, and some of the people in the store on a given afternoon are there because of the videos rather than because of a dance in April.
