Tape or glue??

For what purpose?

Topstick Toupe Tape is way better than any fashion tape because it is made to withstand moisture.

If you are looking for boob tape, brassy bra is awesome!! The longer you wear it, the better it sticks, so if you start sweating, the heat makes it stick and it's waterproof. You can also cut it to the shape you need

View Quoted Comment K, but why have I never even thought of this?! It's brilliant lol

I've used Hollywood Fashion Tape, it's great for lightweight fabrics, plus it is very affordable and easy to find, but it wasn't up to the task of holding up my whole dress. Whether it would work for you would be based on what you need it to do
