Vince Boyfriend Pant (size 2) or find here
Anthropologie Current/Elliot The Captain Trouser (size 0/25)
These definitely feel more casual to me. This is a size down from what I usually wear in denim (26). The crotch looks better on these but the leg is definitely less slim - more straight cut down from the hip instead of tapered over the hip and down the leg. On the other hand, I like the lack of buttons on the backside.
I don't know, I like both pairs and my instinct is to keep the Vince ones so I can wear them to work or in a more casual manner.
