Does anyone have any experience with alterations though AA? I'm a little worried...the sales person convinced me to order a size 18, instead of a size 14 (I wear a street size 12). Even when she showed me the sizing chart my biggest measurements were less than the size 16. I'm concerned that they do this to try to get more money out of you for alterations, and I'm also afraid I will lose details on the dress if they have to alter it so much. It's already being sewn, so there's not much I can do about the size...but I just have this uneasy feeling about it.
