This bra has decent support, but as other reviewers have mentioned it is very difficult to put on and off. It's also very uncomfortable--the side wires poke in certain positions.  My 14 year old daughter wears a bra 24/7 and this is the first bra she's not been able to sleep in.  She also says that while it's OK for competitive trampoline training, it's not comfortable during certain conditioning training--such as pushups, situps, crunches, etc. because it pinches. Also she says it's very very hot and doesn't seem to breathe at all. I bought this as an everyday bra for her on a trial basis after she outgrew her last bras.  If she liked it I was going to buy her more of them. Since she was left with only this bra she decided to sleep braless for the first time since she was 11.
