I read all these reviews and still went to Gesinee's because they were convenient. They do have a large selection, at least. I went in expecting the worst and armed with my closest tough friend, my mom, and a printed out list of every dress I wanted to try on so they couldn't push me around. I ended up with a very nice young woman named Silvina who listened to what I wanted and the dress I ended up selecting was actually one of her choice, not mine. My mom was so impressed that we went to the MOB section, where the lady with big hair and red lips did try to bully her into trying things on she didn't like. My mom basically yelled at her to back off. Their ordering process is very clear now, in that you make the decision about which dress to buy (they definitely don't make it for you and they make you sign off that you agree to ordering size x). Clearly they have been burned or have burned people before with the ordering thing and so they've set up a system that helps them/us avoid this issue.
I am not using their alterations out of fear of the horrible reviews...I'll go find someone else to use instead.
