I do love these things but some of the other reviews are a little over doing it with five stars.
This product does not stick to all fabric types. I have a few bras with slightly silky textures and the tape never sticks to them.
Also a big thing is that these HURT when they get stuck to your skin. And a few times while trying to put them on the right place I'll wear out some of the stickyness.
But for the most part this does work for a variety of clothing's and does keep them in place.
