Lululemon Striped Long Sleeve Boat Neck top Small

Lululemon Striped Long Sleeve Boat Neck top Small This shirt does not have any inner tags for size or care instruction. I tried it on, seems like a small. Fit me, but very tight (150lbs) Softest shirt ever, in pristine used condition. Thumb holes in sleeves. Top of sleeve comes down to knuckles. Small key pocket with zipper in back. See photo--pocket is not deep. Goes only to my second knuckles.
