Your dress is beautiful. I think we all have those second guessing moments. Also if you don’t have any luck with Wed2Be, there’s a private selling group on Facebook. I know you won’t get the full amount back but better than nothing?

Definately prefer your dress. Maybe try a belt. I wasn’t going to wear one because I have a short torso and I loved me dress as it was but when I tried it with my dress I really loved it. My dress was a size 22 and I’m a 16/18 normally. Have you considered wearing a cathedral veil? I found mine made me look much more slimmer and gave me the additional coverage.
Just wanted to say your dress is gorgeous and really suits you, you look really slim in it! Sounds like you're just having dress wobbles, we all do and hopefully they will pass soon so you can relax and enjoy yourself!
Beautiful flowers, are they artificial or real? Whatever you pick will look lovely but I like the second the best.
