I have a couple of sports bras from Road Runner Sports that I love- they're the only one I found for larger cup sizes that didn't have some sort of clasp or zipper that makes it look like underwear (I like to go shirtless sometimes in the summer). They used to have them in a wide variety of colors, but now they're only in black & white unless you want the long version: RRS Sportek c/d cup

The description says for moderate-impact activity in larger sizes, but trust me, if you're wearing this thing, they aren't going ANYWHERE. I use mine for trail running and usually refer to it as my bullet-proof bra
