Maison Margiela Straight-Leg Cotton-Canvas Trousers
From MR PORTER
Maison Margiela's trousers look like classic black jeans but they're made from cotton-canvas rather than denim and have stitches detailing the waistband in place of a logo patch. The relaxed, baggy shape works well with a loose flannel or layered T-shirts. Large to size. See Size & Fit notes.
