I bought these for long international travel days and they're so comfortable. I bought a khaki pair in Large, petite, straight leg. I forgot to be mindful of undergarment color and wore black boxers, but they didn't show. I am 5'6", 147 lb, muscular/athletic build (usually a 10 short in jeans), 38" bust, 30" waist 39" hip, and these fit just right. Decent weight for moderate climate (comfortable 50-78 degree temps). Functional back pockets, deep front pockets, but just be aware that everything shows. Underwear lines likely, anything in your pockets will show. I had to sprint for my gate in one leg of this trip and these pants took it in stride (literally). Dried quickly (because sweaty), and no odor. Coffee stain washed right out. I would wash these inside out in cold and line dry.
