A term that made its way into this vocabulary in 2015, the wallet-on-chain is an ingenious way to carry your cards without the need to hold anything. Ideal for nights out when dancing is necessary and carrying is not, the wallet-on-chain silhouette is simply a wallet attached to a chain. Typically made from leather, suede, pony skin or faux-leather, it comes with enough pockets for your cards, with some offering space for your phone, cash and lipstick too. KENZO's Kalifornia, Stuart Weitzman's Chelsea and Proenza Schouler's PS1 create the wallet-on-chain silhouette with just the right amount of details.
