Been paid but still broke? Well, here's a super-easy super-hot styling tip that will cost you pretty much zilch if you know the right people, courtesy of RiRi’s just-released FourFiveSeconds video. Just take one large men’s denim shirt – any boyfriend/dad/brother/housemate/male acquaintance will have one of these lying about – and wear it unbuttoned to the navel. Then, take your favourite belt and secure it tightly around your waist – extra style kudos for doing the twist and tuck. Match with some boyfriend jeans (all the denim was FourFiveSeconds collaborator Kanye’s idea, appaz) and a pair of chunky boots (RiRi's are by Timberland). Accessorise with delicate jewellery to offset the utility wear. And yeah, that’s it. You don’t even need a bra for true RiRi vibes.
