I went to mostly places near me and not in the city, but here's what I can remember... I was also looking for a specific style that wasn't widely carried, so I had alot of trouble finding anything with a slim silhouette, and lace and beading.
Harleysville Bridal - the selection was pretty good. Mostly current styles, the people were nice. Really small shop. (I like small shops as opposed to the large warehouses). Prices seemed the same as elsewhere - average was around $1,000-1,500. I would have loved to support this store.
Ann Baileys - Doylestown - this is where I found my dress and they had the most that were in the style that I wanted, I swear I think I could've bought like 4 dresses from there. Kinda expensive though.
Country Bride - Bensalem - blah. I didn't like anything in this store and I didn't really like the people so much either.
Bridal Town - Skippack - this place looks like it is off a horror movie set. My sister got her dress here a few years ago and it was gorgeous, but they did not have 1 dress that wasn't puffy. Not one in the entire store. There were a few pretty puffy ones that I tried on that I even liked, but it didn't fit what I was looking for. The place is really weird looking though.
Sabrina Ann - Ardmore - Consignment bridal shop, wedding gowns. Ardmore, PA. - This is a bridal consignment shop and the dresses in the store were of really good quality. She will even take your name and contact you if something similar to what you are looking for comes in.
Eliza D - Montgomerville - this is mostly a bridesmaid store or if you are attending a wedding, but they had quite a few that could pass for bridal if you didn't want something too bridal-y. When I went there, I almost bought 4 dresses, cuz they were under $300 a piece and they were nice. The designer for a few of them was Scala.
That is all I can think of for now...
