No wires, no squish, no push, no pull. It is the most comfortable bra ever... I sleep in these a lot. The material is soft and stretchy and the bra gives just enough lift that I can feel comfortable wearing it as a most days bra. I'm pushing 40 and have traded my lacy, sexy, push up, cute print, funky color bra's for these. It's not a push up cleavage bra, definitely not a sports bra, and I love them. It shows you nipples though, so if your bothered by that kind of thing.....
