The '90s are back in action, and here's one supereasy way to channel the trend in one minute flat: wrap a shirt around your waist. If you're looking to emote that cool Johnny Depp 21 Jump Street style, then pair a plaid shirt with denim shorts for full-on grunge appeal, or take a more subtle approach and style it with trousers and a sheer blouse. Even more, you can swap out the plaid option for an army-green shirt for a slightly less obvious take on the trend - we love how Alexa Chung paired hers with a cute short set. Just remember, the key to getting this right is choosing an oversize silhouette (the shirt should hang around your knee area), and don't forget to snoop around your boyfriend's closet for an unexpected score before hitting the shops.
