Seconded. Old-school leather saddles are pretty good for riding in street clothes. But, they do tend to require a slightly different fit - I never managed to run one with my normal saddle-bar drop - the Brookes really wanted saddle and bar at the same height and the nose of the saddle pointed up a bit. This was good for ~2 hours or so, never tried it for longer, since I had normal road bike with normal saddle for that.

Mine is on a mountain bike. Ride 3x per week, two-hour rides. Still hurts when I switch to someone else's bike/seat.
