Set of two: black and navy. Features an elastic waist and back pockets. Worn for one season. While there are no visible stains or pilling due to the nature of the colors, there may be some slight fading. Please check the photos. Size 90, but with a short inseam (approximately 18 cm). I think they are 3/4 length. For comparison, I've photographed them stacked with a size 90 pair of pants from UNIQLO. See photo 6.
