Wedding Dress Question

Does anyone happen to know if it is difficult to take a dress out if needed? When the bridal suite ordered my dress, they ordered the size I had tried on which fit me perfectly. Now, when I think about it, if I accidentally gain 5 pounds, it might seem tight. I asked them about this, after the fact, and they said it wouldn't be a problem to take it out. I just wanted to know if anyone went through this or knows about it. I am just afraid it might affect the dress, although they said it wouldn't. I'm still eating french fries with gravy though!!

I guess it depends on how much weight because in reality they can only be taken out so much before it's a problem. But it can be done - 5 pounds should be fine - 10 might be tricky but don't stress.
