Glad i went in to buy this: in store i was surprised by the texture which was much more cotton (almost gauze-like) than most cloth & stone shirts made with tencel. the blue looks like demin online but in person is a rather ugly dark blue, the pink was almost red, but the yellow was beautiful!
it is double-lined which is one of the best things about it. 
i'm usually between a s and m and could have gone either way but choose m because it was a little longer and "flowy-er".
