Bought two years ago, this is an expensive pair of trousers from the high end "Homme Plus" of the Comme des Garcons label. They are made from a thick polyester fabric which has been died black after manufacture which gives the distnctive yellow tinge to pocket linings and labels. They have a deliberately creased appearance. Never worn very much because they are a bit long in the leg, they are in good condition apart from some tiny plucking below the left back pocket - shown in last photo. Labelled a size L, I think they would best fit someone with a 32 in or 34 in waist.
The exact measurements when laid flat are. Waist seam to seam : 17 in / 43 cm. Inside leg length: 35 in / 89 cm.
