I use denim as the lining for many of my bags, the color hides dirt from scuffs and it's sturdy and holds up to wear and tear. So what better fabric to use for a jacket? This denim in particular is super soft.
I have it listed at LouLouBell Baby and will be hoping to add others soon. I'm waiting for a ginormous order of some really great children's fabrics, so lots of new ones on the way!
