Mine is en route, but I may still be able to answer your question. BlueSeventy definitely cuts "lean." So the sizes are designed around a pro-athlete body type. If you look in the mirror and see Bruce Lee, then size down. Otherwise, I'd size up. Especially since you'll likely be wearing clothes under it for any race without a changing tent.
