Ever questioned the power of a one-item wardrobe overhaul? Check out model Karlie Kloss. The archetypal girl-next-door had a real fashion moment this weekend by tapping the trend for all things logo-printed in a super pretty way. Attending the Vogue Festival in London, Karlie wore a pair of next- season Ashish boyfriend jeans with sequin-embellished slogans and knee rips and - showing  how to make the high-fashion jeans highly-wearable - she paired the denims with go-to girly staples (a round-neck jumper, pointed court shoes, delicate gold necklace and bracelet). Overhaul, completed. 

Alexa Chung also gave good style at the Vogue Festival. See how she worked a slouchy mac and shirt, here.
