If you are wanting a good tape to start with, try gorilla tape at home depot. I think they may make in pink, but better than duct tape, and less harm on the skin if you are sensitive. I used it for something else but it holds to the skin better than other tapes and glues if you shave and prep the site w alcohol. If it has to be double sided, maybe glue 2 strips together in advance? But the trick to make it adhear longer, or at least for me, I used one of those sewing things that looks like a spur and perferated a bunch of holes in it to allow the moisture to drain. Otherwise it builds up and the tape falls off. Also the tape can only be used once, your outer skin layer will clog the surface.
I used to work w alot of polymers and tape before this. Hopefully this helps;)
