Just want to ask all the brides out there. Have any of you thought just before your wedding that you may have picked the wrong dress? I am getting married in less then 2 months and I bought my dress about a year ago, my dress was nothing like I thought I wanted at all. I tried on a few dresses of the type I thought I wanted but there were just not right and then tried on the dress I bought and the lady in the shop said my face just lit up. Each time I try it on at my dress fittings I feel great but the time in between and looking at photos of me in it I feel like I should have tried on more dresses or that maybe this isn't the right dress and I worry my h2b won't like me in it. Has anyone else felt like this?
