I keep mine on until bedtime which is when I change into my PJs. Mine have never been that uncomfortable where I couldn't wait to take it off. Some of mine are even underwire bras.
I'm wondering if people that rip them off ASAP because they're uncomfortable are wearing an incorrect size or something.
