I bought this because it was very cheap and I had a backless dress that I couldn't wear a bra with. It works well and sticks on the entire day. The only problem I had with it was the fact that it kind of made me sweaty but regardless of sweat, the bra stayed on. When it comes to washing it, I just put it under some warm tap water and put some soap on it. After it dries, it is good as new!
