Rios
A slim straight with a touch of taper below the knee: Freenote’s neatest everyday cut.
For a 81.3 cm waist (our default: enter yours). Size 31’s waistband measures 81.3 cm, right at your waist. Selvedge gives about an inch with wear, so a waistband that starts at your waist ends up comfortable, not loose.
