This is beautiful! I did see in the reviews where the crinoline or petticoat does not come with the dress? Do you have one, or can you find one to buy or borrow?
One caveat about Sammydress, they have terrible online reviews, and my Bf's was one of them. He was being a sweetie and ordered several dresses for me. They charged his Amex immediately. Six weeks later, we still did not have the dresses -they ship from China - and repeated email queries went unanswered. He called Amex and disputed the charge successfully. Only after that, did we get an apologetic response that the order was cancelled. It had not even been shipped yet.
I don't want to take away your joy, but there seem to be a lot of these reviews for Sammydress in third party sites, so if you go with this dress, use a card that will let you dispute the charges if it never arrives, and give yourself a good amount of time to receive it.
