The material is quite decent, thicker than some other satin pajamas but my issue is with the style and sizing. The legs are very wide, not typical of a woman's style, but more boxy like a man's style ( perhaps this is unisex ? ). The waist is 29 inches but stretches easily to 38 inches ! The inseam is 29 inches. I am not a seamstress but these are the measurements I got. My evaluation is that they would fit a large person better than a medium.
