I really like this bra to my utter surprise.
I've wanted a mesh bra for a while but was afraid that it would be flimsy and trash. Delightfully surprised to be wrong.
This bra is supportive, lightweight, and pretty comfortable. The mesh fabric is woven in such a way that it doesn't bag out the way other mesh bras do. The down-side of that is I can see how this could cause overflow if the cup isn't big enough.
Now, when I say it is supportive, what I mean is, it holds my breasts up in the position they should be, BUT it does allow a fair amount of bounce and wobble. For reference I am a 38DD.
Give this bra a try!

This bra is sexy and comfortable. I like as little padding as possible while still having some sex appeal and support. The underwire lifts without being uncomfortable and the mesh is just enough to keep nipples hidden under shorts.

Great, unlined bra. Fits my somewhat wide spread breasts 38C, very nicely. Perfect fit, hard to feel it's even on sometimes. Most wires did into under my arms, but not this bra. Reviews said it was really soft material and stretchy. I'd say, not high end fabric, and I am so suck of lace--whose idea was it anyways, to make lace a standard component with lingerie?! However, it has a good stretch and fabric isn't scratchy at all, feels like a lot of cotton, and washes great. Good for the price as well
