Okay since I voted and apparently didn't say anything I'll have to wing it cause I don't remember what I said
Speaking as someone who is a C cup, I can honestly say it's big enough! I'm 5'8 and it suits me, a D cup would be nice, but we can't always get what we want! (Damn!)
Anything over a D sounds like pain. I know I have a little bit of lower back pain, but it's mostly from carrying my boobs and my huge butt! LOL!!!
