Review (3/5): Hard to apply and didn't stick to skin
First, I had trouble separating the backing from the sticky tape. I have very short fingernails because I type fast and accurately (but not with long nails) and I play guitar (chording needs short nails). Perhaps if I had long nails it would be easier to remove the backing. As it is, I ruined a couple of strips before I was successful.
Second, after prepping my skin with an alcohol prep pad (just in case), I taped a very-low-necked top to wear on a moderately warm day. I was out in an air conditioned car for about 20 minutes. When I got home, the tape was still stuck to the fabric like a trooper, but not at all to my skin. In fact, I had to work a little to get the tape off of the fabric.
In the future, I'll try to stick fabric only to fabric, but that may not always be possible depending on the garment, and don't think that is the way this stuff is supposed to work. {Edit: I did try this and, again, the tape stuck to the top garment but not the garment beneath it. Drat.}
I do have sensitive skin and the tape didn't bother me, so 5 stars for that.
