on a happy note (with question at end)

i had my third (and last) dress fitting last night ... and the seamstress told me i lost weight and if i gain a pound, the dress would fit better .... i'll pass on that one, but thanks



now the question ... they said they'll press the dress and i'll pick it up a couple of days before the wedding ... obviously this is standard ... but they said i can't try it on again (or if i do, they won't re-press it) ... is that normal? what if i gain/lose a lot of weight? i won't know till my wedding day?
