I got mine today! I had to drive 50 miles to the nearest VS... got there, and all they had was a 32A, 34C, and a ton of D sizes... I'm a 34B so I was pretty sad, so I went back to ask a SA if they had more... and she passed along this tip: most people buying them are buying one or two cup size larger than they usually wear to avoid the "muffin top" effect... so I tried on the 34C and it worked!
Holy crap padding, tho! But definitely a nice effect! I'm skinny, but with wide hips, so it helps balance out my hips. Also gives nice oomph to some of my dressier shirts. I'm excited about it!
