I purchased the White/Gray in size Large.Approximate measurements laying flat unstretched:Chest underarm to underarm 20"Length shoulder to hem 29"Shoulders sleeve seam to seam 17"Sleeve length shoulder seam to cuff 26.5"After a cold wash and hot dryer it did shrink slightly, chest 19.5" and length 27.5". It fits fairly true to size, more like a slim fit style. The waffle knit is quite thin and the waist of dark jeans can be seen through the fabric. This is probably just with the white, I think the darker colors would be fine. Overall it appears to be a fairly well made top but I would recommend up sizing for a relaxed fit.
