Black Long Sleeve Horse Themed T-shirt

Received as gift but appears to be mismarked size.  This is why I stated XL in description.  I am 5"11", 160 lbs and swim in it.  Length 28.5", across the hip 22", sleeves 24.5" inches.  Unable to return. Fits more like a men's XL in either Hanes or Gildan t-shirts. Solid black on reverse. Dressage fans, here you go!
