I LOVE these tops; I own every color, even though I'm not a massive fan of the white and pink tint. I wish there were darker colors like wine, navy, etc., so it's not as noticeable or glaringly obvious when I sweat through these tops. They're not a 5-star item because, as another person mentioned, the neck opening sucks. I get why it can't be bigger as it would take away from the aesthetic but come on, give us a zipper. The comparable swimwear top has one, and when you think about it, when you wear these tops you pretty much get drenched in a workout (or at least I do after an hour working out doing HIIT). So putting it on is a bit challenging, and after a sweaty workout, it's even worse, but man, this top is so fricking flattering; I'd buy more if they came out with other colors, even with that slight flaw. Support-wise, it's good; I primarily do HIIT and running on the treadmill or floor exercises that require quick movements (like burpees), and I feel supported though I am not endowed with a fuller chest (B-cup here), so for those lucky ladies who have a larger cup size, I'm not sure how these would work in a moderate+ workout.
