Welp, I ruined one at my first attempt to use as I had to reposition and then it did not want to stick. Second attempt worked out fine and they stayed in place despite the fact that I was on the dance floor all night; jumping all around; and sweating! I did have to cut a bit off from the outer edge to keep them from showing as I had a backless dress on. I cut away the excess after they were in place. While I did pack baby oil for the removal, they seem to peel off without any trouble so I did not use the baby oil - mistake. I did get some blistering in one area on one side which had I followed the instructions probably would not have happened. Would buy again!!
