Cool rock and roll jeans.
Size: 34, Color: Black
Very true to size jeans. I'm 6'1" 180. 34" waist is just a little loose. With a belt it's perfect. I'm usually a 32/33 so the sizing is right on.

Slightly smaller than expected
Size: 34, Color: Light Grey 870
I wear a size 34, but these jeans fit like a 32. I'm 6'4" and the length, looks better in mid to high top shoes. I would suggest going a size up.
