I'm 175 and 6ft 4in tall. I often buy medium and large shoes depending on the brand, but I usually try them on in the store to be sure. I took a chance using the environment for one of these and it works great. It's a little tight, but not enough to prevent me from wearing it. I have a small tummy that moves away from working out but hardly ever shows up. If you like tight clothes choose Medium if you are my size. I don't know what the plus size looks like, but I bet it would sit pretty loose on me. A few months later (edit): A shirt slipped into the dryer and shrunk so much that I can no longer wear it. The other was a little rubbed near the neck after 2 washes. What can I say, these are cheap shirts and their production is not going according to plan.
