Levi's "517", a rare pair made in the UK with a back button marked 299. Although they are 517s, they have the straight leg of 501s. The button fly is also unusual. I bought them in Americamura and wore them once or twice, but they've been in my closet ever since. Rise: 31cm Inseam: 79cm Waist: 40cm Leg opening: 21cm *Please note that these are amateur measurements taken with the garment laid flat, so there may be some slight variations.
