The fit and comfort of these pants are unfathomable. There's no zipper, just a waistband that makes you feel good even after a large dinner. I usually wear size 29 pants and these fit perfect. The bow at the front allows you to tighten the pants, if need be.
I wore these pants on two different occasions and changed it up with the first time wearing it the with the bow in front, and the other time with the bow in the back. Super versatile and can dress it up or down!
