I have never bought a dress from Kay's for any formal I have gone to, because I think the prices are too expensive. But I found the service to be excellent, whether you get your dress from her or not.
I had alterations done there for a few formal gowns, and the work was always top notch and always done on time.
Every person I know (and there are many) who ever rented tuxes from this shop were well satisfied with the pricing and the service they got from the sales staff.
Excellent location, good parking, and normal hours for a bridal shop.
