Having seen that lovely little number,I'm torn between screaming "YES,YES,YES,YOU'LL ROCK THE JOINT!!!" and demurring because it has a white background,and only the bride should wear white at a wedding (and you don't want to upstage the bride, such poor form).
Maybe you could get around it by wearing a black lacy wrap,to balance the white part. And don't forget to pull your hair up and wear some sparkly chandelier earrings(look at me ,all excited getting you dressed up for the wedding and haven't even seen you - ah,women!)
Here's hoping you snag your own man at this wedding,I just know you're going to look fabulous!!
KEEP IT REAL!
