Oh, wow.  I bought a size up for my mastectomy surgery next week so everything will be loose, but these pajamas feel so good I may buy my correct size for later. I'm 5' 9" and weigh 180.  My correct size would be probably be an XL, but this 1X will be just right for the weeks following surgery.  Maybe I can dry it when it's time to go back to my regular size?  Anyway, the stretch is lovely, the color (coral) is beautiful, and I am very pleased.
