Wedding dress issues

It could be because you built muscle. And yes, they can let it out depending on how close it is to zipping

Most dresses depending on manufacturer can be let out 1-2 sizes.

I would definitely check with your seamstress about the letting it out or adding a corset. remember although you lost weight, you probably gained muscle in those sames area which added some new inches you weren't expecting.

My dress was big when I brought it in and my seamstress told me that was a good thing because it's super difficult to let a dress out. I'd look into the corset option but if you've been actively working out and eating clean, I'd put it off for as long as you can so your weight will be more accurate. Good luck

First of all, I would take a deep breath and relax! Your dress definitely be made to fit you, do not worry Seamstresses can work some serious magic and make anything you can dream happen! You have time to make sure your dress fits you perfectly. I do agree it's most likely because you gained muscle. But they can certainly let your dress out or add something to make sure it fits you perfectlly. Beautiful dress, btw!! I had a friend who bought a dress and it was literally 4 sizes too small, some how her seamstress made it work!!!
