Roberto Cavalli is often spotted in his signature denim button-down shirt which he almost always clashes with jeans so much that fashion industry players have come to associate him with this style. On his recent trip to Lagos, he once again went denim-on-denim. Recently, a whole lot of celebs have been playing with this trend. Contrasting shades of denim seem to work much better. Funny but a lot of blondes seem to love this trend!
