It is very possible to find a flattering jersey and they are so much more comfortable than riding in t shirts. I am 5'10" and a size 14. I was a bit appprehensive about wearing a jersey initially. Funny I had no problem with the tight shorts and initially rode with cycling shorts and T-shirts. Then as the weather kept getting hotter I decided to try a cycling jersey. I now own several (OK more than several, it is becoming an addiction) and find they wick away the sweat,provide a great place to keep things, and don't blow in the breeze.
