There's no doubt about it, belt bags are back and here to stay. Gucci's 'Marmont' version has been made in Italy from chevron-quilted leather in a versatile hue the brand calls 'Porcelain Rose' and is decorated simply with the signature antiqued gold 'GG' plaque. It's sized to hold just the essentials and can be worn a variety of ways - to go hands-free, buckle it high on the waist, low at the hips or coolly slung cross-body.
