ST. AGNI's 'Petit Belt' sandals look so good with tailored pants or a slip dress. They're made from recycled-twill and leather and have elasticated slingbacks for a secure fit. We love the combination of slim straps and 10mm kitten heels. Lower-Impact Materials. This product is made using at least 50% lower-impact materials oringredients.
