When British designer Anya Hindmarch sent her cereal box and sticker-bedecked bags down the runway in September, Instagram erupted in a frenzy. The bags have since been spotted on many, but the most adorable accessories from the collection are the leather stickers. Developed in collaboration with stylist Charlotte Stockdale of CHAOS FASHION, ‘The Sticker Shop’ includes smiley faces, speech bubbles, weather symbols and individual letters. We’ve also spotted them on the NYFW sidewalks, monogramming Hermés Kelly bags on blogger Adi Heyman of Fabologie and Nasiba Adilova. We’re betting there’ll be more to come during London Fashion Week, which kicks off today.
