Oh I adore this shop in Montreal it is such a gem with something for everyone. The top floor is Boudior 1861. There you can find gowns for events, weddings and more. I have found a lot of decent priced formal great gowns. The prices start at $69.00.
The middle section is more dress down and casual but as well they have some more formal attire. They are always busy and pumped. If you see anything online get in as soon as possible as it will sell out fast.
The bottom floor is the sales room. I have found gowns starting at $10 regular priced $100. Along with shoes, designer clothing and more. The sales staff are great and very helpful. As well it has street parking.
I highly recommend this shop as they will do everything to help you be satisfied !
