If the house of cb's dress has been living in your head rent free but you're broke like me get this dress. It is a great dupe. It is beautiful. The only notable differences I can tell is that the lace in the back isn't perfect but you can easily replace it with whatever lace you want. And the fabrics on the bottom and the top aren't the same. I am 5'9 and 200Ib and ordered a large. It does have some stretch but not a lot of support.
