So i found a beautiful Valentino dress on eBay. It's sooo gorgeous. AND marked down from $10,000 to a few hundred!! However, there's only one and it's size 12. I'm a size 4, give or take. Is it possible to alter it to be my size. I know there will be lots of extra material but that's ok, it will make the dress poofier, right? Or would it just look weird? Thanks for the help..!!
