I wear a 32 B and have always been a bit of a bra snob. I've usually paid a mininum of $50.
Yesterday, though, I tried on a Calvin Klein demi-cup (which I usually avoid like the plague because I have shallow breasts). Shocker, but it fit like a dream and super comfortable. Excellent reviews, too. They are $33 at Amazon with free ship and returns if you're Prime.
