Anyone? I'm thinking it's a Tepphar, but no idea on the wash - Likely from a recent season too, since I took the pics from a pair currently on sale at farfetch.
I'll have to disagree here, I often reduce the waist on my jeans because my waist is apparently disproportionate to my thighs according to denim makers. If I size down, my thighs don't go through the jeans at all...
