Other Halter unclassified dresses

I bought this one-of-a-kind dress in March, & found out I was pregnant in June. I’m getting married in October, & no longer fit in the dress! I’ve only tried it on 3 times- twice in store, & once at home. It’s been stored in a garment bag, in a closet- of a non-smoker, with no pets. It hasn’t been altered at all, & looks exactly as it did when it was first purchased- which is STUNNING. I’m heartbroken it can’t be mine, but will happy sell to a bride that falls in love with it as much as I did! $1,500 OBO!!!
