I'm 175 and 6'4". I often buy medium and large shoes depending on the brand, but I usually try them on in the store to be sure. I am took a risk using the environment for one of these and it works great it's a little tight but not enough to deter me from wearing it I have a small tummy that takes away from working out but barely comes up. If you like tight clothes, go for medium if you're my size. I don't know what the plus size looks like, but I bet it would fit me pretty loose. A few months later (edit): A shirt is slipped in the dryer and shrunk so badly that i cant wear it anymore the other one was a little rubbed near the neck after 2 washes what can i say these are cheap shirts and their production is not according to pl on running.
