I am in love with Maggie Sottero's Bernadette:

I love the lace, and the sleeves, but I don't feel comfortable with the open keyhole back. Does anyone know of any dresses that have a similar look with the sleeves and lace, but not with the open back. I hate the way that cap sleeves added on to strapless dresses looks, so that's out. Or how hard do you think it would be to have the back filled in? TIA
