A blue jean jacket is and will forever be a staple in your wardrobe. You can wear it year-round, layer it over practically everything, and sport it for nearly every occasion, whether it's an early morning brunch with your gal pals, a day of shopping, or a fall tailgate. Sometimes, however, a blue jean jacket can end up feeling a bit too casual. That's where a denim jacket in black comes into play. It's an autumn and winter layering piece that's dressier and edgier than its blue-hued cousin. Case in point: the below black denim jacket outfits. From looks that pair the dark-hued staple with flowy, floral dresses to ones that combine the cool jacket with track pants and other athleisure items, these are the ensembles to take note of.
