Creative director Emma Hill named the leather schoolboy satchel with belt-buckle detailing after Alexa Chung, who wears the bag in various sizes.

The brand, founded by Roger Saul in 1971, was an ailing British leather goods company until Singaporean businesswoman Christina Ong took the brand over ten years ago, investing $10 million in the company.
