Chylak's belt bag can be styled in so many ways - Alexa Chung likes to wear hers cross-body, but you'll find plenty more tips on the label's Instagram feed. It's made from glossy croc-effect leather that's been stamped with a unique serial number indicating the collection and year of production. Despite its compact size, there are two compartments and a zipped pocket inside. Wear it around the waist, or remove the strap to carry it as a clutch.
