I am 5'8 and a size 4. It's rare that I find pants that fit me comfortably in both length and waist. These pants are AWESOME. They are more than long enough and extremely comfortable! I ordered them in White and the fabric is thick enough to not be ridiculously see through. I wouldn't wear red underwear or anything, but totally do able with sensibly colored undergarments. I would  definitely order again. I may order a pair in another color, in fact!
