This is a pretty nice small band / large cup sports bra if you have narrow breasts. I would prefer something wired but all the major brands have gore widths that are much too wide for me.
Pros: Well fitting band and very supportive. Comes in a bajillion colors. Cons: Definitely squishes my boobs together.
Other reviews are accurate that the bra runs a little small. I made the choice to size up the cups instead of the band and that was definitely the right choice. The band fits very nicely. The neck is pretty high - it makes it supportive but maybe less "cute". Check ebay for good prices as well.
Reference: my standard bra is the Cleo Lily in 28G.
Technically, this bra fits, provides adequate control, and all that jazz. However, the way it mashes my boobs down is unnatractive and feel sweaty and constrictive - my breasts get mashed downwards and against each other, which is bound to get real sweaty, real fast.
The sort of racer style back holds everything in place, but presses down uncomfortably on my shoulders. There's a sling contraption inside but it's non obvious how it's supposed to interact with my boobs - it just sort of mashes on top of them.
I've yet to find a comfortable, supportive high-impact sports bra in my size. This one certainly isn't the worst, but it's not winning any awards either.
