Does anyone know of somewhere locally where I can get dress alterations for fairly cheap? I don't think I need anything complicated. My zipper broke when I tried on my dress (I bought it online) and it's a little tight in the back. I'm thinking it would be easy to add some fabric in the back with lacing to make it into a corset type back, so then there'd be some give and take with the size. I'm also thinking of adding a bustle for the reception.

I don't have pictures of me in it yet because I just got it, but here's a link to the original photos from the seller:  http://classifieds.weddingbee.com/topic/lazaro-3813-replica-gown-size-8?replies=2
