Has anyone changed experienced changing a zipper back to a corset back before? I bought my dress secondhand in September and it fit 100% perfectly, but when I tried it on today, I found it's too small in the chest area and won't zip. Is changing the back a complicated process, and will it fix my problem?
I'm hoping to call the alterations lady tomorrow, but it's not really pricing that I'm worried about -- I want to make sure it will work to make the dress fit! I'm hoping that whether I lose weight or not, the corset will solve my problems and let me stop worrying. I haven't really be insecure about my body since high school, but after buying a dress that four months later doesn't fit, I've been feeling very self conscious, and extremely aware of my weight -- and worrying about my dress is totally not helping. 
Also, previously, the only alterations needed were to add a bustle -- can I still add that with a corset back?
I've attached two photos of the dress if that helps in answering the questions (not sure they're great photos though) -- the one of the front of the dress is from when I bought the dress in September, and the one of the back is from when I tried it on the first time last March.
Anyway, thanks in advance for the help!
