The more slim you are...the more true-to-size things tend to be with fitted-garb labeled "aero" or "race"...tags sellers tend to tag to get more hits. Between Pearl and Chinese faux-Pearl or faux-Rapha jerseys, the difference is the quality of the zipper and to a small degree the quality of the fabric (also the Pearl tends to be cut a bit longer in the torso in aero/race-cut jerseys)
