This is a great resource, thank you. Being tall with a long torso, trial and error buying t-shirts has been torturous and expensive.
Then you finally find a shirt which is just the "right" length at the store, and three washes later and it is too short... But you cannot buy the next size up since you need more LENGTH not shoulder width.
Very few brands make t-shirts which are 2x-tall (as opposed to 2x-large, where both the length AND width increases). A medium-2xtall would be like the unicorn of t-shirts.
The sizes should be: S, M, L, 2x, 3x, etc & S-T, S-2xT, S-3xT, M-T, M-2xT, etc.
It took me forever to find a fairly athletic fit (slim but not skin tight) in my height (6'2" with a long torso) that also doesn't have logos or random graphics (solid colors and maybe a pocket is all I want).
If you have a favorite choice it'd be great to know it and have more options.

Try RibbedTee.com. Esp. the Micro Modal shirts. Yes, they are expensive. But they last and fit.
