Wow that's amazing, the dress is beautiful and it's practically free! I would have even been happy getting the ones around $125 you mentioned but I can't be bothered with ebay lol - mine was $500 and I considered that a good deal, in the area I grew up in and where we were having the wedding, dresses are on average around $900+
Anyways, hope it works out but like you said, if it doesn't, it was only $20.
