I'm 5'8 - 38"?30"?38" - i bought these leggings in a size large (blue motif) to wear under a really cozy organic cotton tunic in an attempt to create a sophisticated-looking, comfortable look. when i first it them on they felt like compression leggings and i wondered if they were too small. i wore them for a day and now they are falling down around the waist and the crotch is hanging. i spend so much time trying to hike them back up - i'm not at all comfortable and i doubt i'm looking sophistica
