I don’t know how the weather is over by you, but here in Boston we are well aware that summer has arrived… and it’s getting out of hand. It’s not the heat I mind so much as the humidity — the sweaty/sticky factor that makes you want to rip all of your clothes off, all the time.
So I’m kind of on a mission to see how little I can get away with wearing out in public. I’m doing the bra-as-crop-top thing on a regular basis, as well as the girl-boxers-as-real-shorts thing. This is a nice advantage of being small-busted: it’s pretty hard for a body like mine to shock anyone, no matter how inappropriate or skimpy my attire.
Anyway. So here’s what I look for in summer bras: breathable fabrics (cotton, mesh nylon, silk); a range of blissful summery colors, from basic solids to playful prints; and simple, lightweight styles with minimal padding and other such nonsense.
That’s why I’m all about these two Aerie bras, soon to be added in the store:

Aerie Katie polka dot bra in aqua/orange

Aerie Hannah Cotton Bra
Both are sold out in size AA on the AE website. The Katie bra is simply delicious in aqua and white, with just a bit of orange lace trim and a delicate, sheer center bow. Hannah in basic navy cotton is a nice alternative to black microfiber for hot weather — it’s a bit softer, more breathable, and less formal.
