I find myself wearing light support sports bras more and more frequently on a daily basis. I've been looking for something with the same comfort that wouldn't give me the 'uniboob' of a typical sports bra. Sizing: I'm 150lbs, natural 34DD (teardrop shape). I found the cup sizing accurate according t...o the size chart. My size fell into the middle of the L range. I could have gone with a M for a tighter band but I am certain the cups could not have been deep enough. Just looking at the L in the package, I thought...this is a tiny bra! Glad I went with L. lol Pros: This is very soft (same material I've had in other light-weight/yoga grade sports bras from ON). I did not feel like I would spill out of this as some large cup reviews mentioned. But for sure this is a very light duty bra...just a little more than a cami in support. Probably great to sleep in! Cons: The bra just doesn't seem to work with my natural shape. The fullness of my breasts is toward the bottom and a little flatter at the top. The bra is not shaped in a way that adds any fullness to the top of my breasts and the top line of the cup creates a bit of an indention where my cleavage would be. This is sometimes referred to as a 'double bubble' if you are familiar. A lot of this has to do with my natural shape. I've run into this sort of thing before with unlined, regular bras. This bra holds breasts in a wide stance and could benefit from a little more gathering at the center...if there was stitching that came up a 1/2 to 1 inch higher at the center, I believe the overall positioning of the bra would be better based on clamping that together with my fingers. And yes I could put in a few stitches...but that still won't add any fullness to the top for my shape. Who is this bra for: I think you might have better luck if you are an A-B cup or if your breasts are augmented to a 'round' shape. Or if you prioritize pajama-like comfort 1st and couldn't care less about shaping/positioning.
