This shoulder bag is part of Balenciaga's cult 'Hourglass' collection, which features sculptural lines inspired by the founder's 'Basque' waistcoats from the '50s. Designed with a curved front flap anchored by a signature 'B' logo, it's made from glossy croc-effect patent-leather and has a chain strap. There's six card slots plus space for your keys, lipstick and earbuds inside.
