Jeans on jeans, tone on tone or a full leather look, there's nothing hotter than an outfit in one material or colour.
I love keeping my outfits chic yet sophisticated by combining items made of the same material. A trashy leather jacket, a leather skirt and a leather cap? Sounds like the perfect outfit to me!
Of course I am well aware of the fact that a rock'n'roll chic outfit like this requires some basic items underneath. Keep it simple and put on a white shirt and plain sneakers.
