I'm sure you love it, but frankly- I think it's awful. It's way too over the top- for ANY bride.
Then again, I also hate the keyhole on anything, and sheer on a wedding dress just oozes slutty to me... but that's a personal opinion. Leave that stuff for only your husband to see...
What is the rest of your wedding going to be like? If that's the only thing that's going to be at level then scratch that idea. I could see JLo wearing that on her wedding day. But, she has the body for that and the rest of her wedding is going to reflect her dress also. You don't have a vintage theme wearing that dress. I would wear that to a party not a wedding for sure. I like the dress though, and personally I couldn't pull it off.
Try Alfred Angelo and David Bridal, and pick up a bridal magazine that has other designers in it. It's not that you'll necessarily find THE dress that way, but you'll start finding a type of dress you like- similarities between them, etc.
