These pants are "true size" which means that unlike many jeans, the waistband will measure exactly the numerical size (i.e. Size 42 measures 42" at the waistband). There is an additional 1" of stretch. Measure your waist/hips where your belt would naturally want to sit, that's your true size.
Inseam is 34" by default, but bottom is serged, so length can easily be altered to a 32.
