Bonday, the gift boutique that opened last summer at Rockville’s Federal Plaza, is relocating to Congressional Plaza with a new name and a new focus on designer goods. “We’re going to be all high-end, both new and pre-owned,” says owner Felicity Tchoufa, who will call her new store Le Bonday. “We’ll have clothing, bags, accessories and jewelry from all the famous designers: Gucci, Chanel, Valentino, Dolce & Gabbana, Versace and Tori Birch. And we’ll also be introducing my own brand, Felicity T.” Doors are expected to open in May or June, in the space recently vacated by Loyal Companion. In the meantime, everything in the original store is on sale.
