Runs much larger than I expected. I am 5’4”& 136 pounds. Usually wear a medium or large in some knit tops. So I need to stitch the side seams in hopes it will fit better. I like the weight and softness of the fabric, but really disappointed in the too large armholes. Unwearable for me until I can sew new side seams.

Runs large with gaping arm holes.

Size: Large, Color: White

This runs extra large and the arm holes are gaping. You can see your undergarments through the arm holes. I am hoping that the shirt shrinks in the wash.
