I initially ordered a large because all my Athleta tops are that size (5'10" 185lbs for reference.) I may have already submitted a review but… I looked like how a kid would draw a shirt on stick people. I returned for a medium, and when that came today, I noticed right away the crew neck was cut and.../or hemmed improperly so it sits crooked on my shoulders. I shouldn't have to go through almost a month of returns for a simple crew neck tee. This entire "Essential" collection is a bit odd. Most of my tops are the "With Ease" cinch and twist tops and those feel like a true large. I would even re-re-order a small but I was worried the arm holes would feel too tight. The cut on the shoulder and torso is awkwardly broad… almost as if a man designed this for himself and just made the arm holes skinnier for a woman. I love supima cotton as it is more durable and less see-through than regular or even pima cotton. I wanted an alternative to all the poly blend workout clothes in my wardrobe. It's a great fabric but I think this whole line needs a little tweak on sizing and overall shape of the garments.
