How I'd style it: 

A denim jacket is one of those items that you will use all year round! It's one of the easiest things to dress in your closet! I would pair the jacket with a mini skirt, a bodysuit, some knee high boots for a dinner, gno, or a concert! A more everyday look, i think it would be so cute with some light wash denim, and a tank for a lunch date or even throw it on with your work out clothes to run some errands! 

Details: 

Button up 

Medium weight denim 

Not stiff- flows with your body, and lays well 

Oversized 

Brenda is wearing size small - recommend getting your normal size. no need to size up for the oversized look!
