David's Bridal in Astoria, Queens

Ladies please help me! I bought my dress at david's bridal in Astoria, Queens and I need some reviews about the place. How are there alterations. also i have to pick up my dress because it came in already and i have to keep it stored in a closet until i try it on in feb/mar so will it change color? has this happened to anyone else? Please answere only if you have purchased your dress at this same location.
Thanks
