I'm 5'7" and 145 pounds.  The medium fits me very well.  They're not sloppy and baggy.  They are fitted along my hips and thighs, but not tight.  They're not that annoying low rise style.  They're very comfortable.  I machine washed then line dried them.  No change in the fit.  Very soft.  I think they're a more fashionable sweatpant, made for an actual woman as opposed to cutting down a men's pant to fit a woman.
