One of the things I’m doing right now is wearing my denim jacket as a layer underneath an overcoat or blazer. I love denim jackets and I feel every man should have a light and dark coloured one in his wardrobe. Layering denim jackets is functional and can look good. Here are a few images from around the web with people layering denim. One of my favorites is to wear it underneath a blazer. For this look it maybe better to use a fitted denim jacket. I tend to have it buttoned up but I also leave it open with other layers below.
