I am a 5'10" size 4 (or 28 long - i need a 33-34" inseam) woman. i bought the s/m and they fit perfectly (with all the excess length bunching at my ankles, as designed)! i'm thrilled. i bought the light color. one thing, wear nude underwear and lighter (or just short) socks - these are definitely see-through! however, i only plan to wear these with long tunics and sweaters anyways - something always reaching down to my upper thighs, at least. so comfy and cozy!
