Hmm, not sure if I should get a small or medium short sleeve jersey. I tend to be on the cusp for sizes. I have a med. Sugoi Bella Jersey that is a little loose on me, a med. Pearl Izumi jersey that fits fine on me, and a small fox jersey that fits fine. I guess that's not very helpful. :P

I'm 5'1" , 120 lbs, and 34A. Any suggestions?
