The perfect cup size in many ways.
They are bigger than an A-cup and you can actually hold on to them but you do not get saggage or stretch marks like you do with larger cup sizes. They fit perfectly in the palm of your hand. You can wear most types of shirts with them.
Dick: Wow, Crystal has really big tits.
Regina: Yeah, but they're probably all stretch marked. You should go out with Letitia, she has a pair of perfect fit b-cups.

The "best of both worlds" bra size-- not too big, not too small. Look equally great in couture coverage or revealing cleavage.
B-cups are the 'Reese's Peanut Butter Cups' of breasts-- sweet, satisfying, and just the right size.
I don't need any padded bras for my B-cups, I like 'em just fine. I'll be rockin' those girls out on the town tonight.
