High-quality pieces that are made from leather require a little care and maintenance to keep them looking their best. In order to keep leather in its original condition for longer, we would advise treating and protecting the material from spills and dirt before its first use. Apply a leather-protecting product regularly to shield against water and stains, and clean using a specialist leather cleanser or take it to a professional. Avoid exposing leather to direct heat sources or humidity. Shop our edit of women's designer belt bags from Stella McCartney for an effortless way to upgrade your wardrobe.
