Bridal Stores (bridal gowns & bridal party gowns)

Hi Everyone,
My friend is getting married next May and we are looking for Bridal Stores in Staten Island, New Jersey, Brooklyn, Manhatten - can anyone suggest places to look for dresses for both the bride and her maids

Any suggestions (or negative stories of places & good stories of places) you can give us would be greatly appreciated.
Thank you so much!
