Good lines was a valuable purchase for me! I feel like I could benefit from a little more practice and the company/reviewer how to videos in order to get maximum shape benefits, but I just used my good lines normal hold tape for the first time with a backless bodysuit, and I absolutely loved it. I’m an Xl/38DDD, and the tape held for about six hours of wear with absolutely no discomfort. I have sensitive skin so I was wary, but the tape didn’t hurt at all at any point, and my skin was just fine ...
