The detachable sleeves make the dress! My daughter looked like a princess in the sparkly Bree dress. We added the sleeves to go with it. Words can't describe how great she looked in them. She received compliments all night long! We did make a minor adjustment to the sleeves and added a few hooks to the top of them to attach to the spaghetti straps of the dress which helped them to stay on all night while dancing the night away!
