Magic!! However I will reccomend testing to make sure you're not allergic to the tape before wrapping your breasts! Stays really well, is double sided, and thankfull they actually thought about how to remove the tape backing (which is usually so difficult on double sided tape)- it's super easy! You can get some crazy clevage with this tape. It also kept my corset up and prevented me popping out for the entire night. Very happy.
