I like the shirt, 100% cotton. Using for bicycling so wanted it loose.  I wear 18/20 and ordered Large plus which says 18 and 20. It fits now but because it is cotton I am sure it will shrink upon washing.  I am returning for a replacement and hope the 1X , which is listed as 22, is roomy.  It is a nice shirt and lots of colors so hope the replacement works.
