Saint Laurent has resided in its own distinctive slice of cool for some time now. Looking for rock ’n’ roll style inspiration? Look no further than the French house’s lookbooks for everything you need. As has been the case for a while, slim or skinny jeans, plaid or wild printed shirts and leather motorcycle jackets (Jeff Goldblum loves his) are the order of the day here. Yes, they’ll cost you a bomb, but they won’t go out of style any time soon either.
