I visited blue owl on the weekend and tried on a pair of super skinny guys.
They fit amazingly.
I've been wearing a 31 skinny guy broken twills for about 6-8 months. I found the leg opening to be larger than advertised (mine measured just under 8'') so i had them tapered down to 7''.
However, getting them tapered by a third party resulted in the taper starting a bit too high, so after a decent walk i can actually feel them tight on my calves.
