Start by considering how much you carry day to day: if you use mostly cards, a compact wallet or card holder may be sufficient, while those who carry notes and coins may prefer a bi-fold or zip-around style. Think about where you will keep the wallet, such as in tailored pockets or in a handbag, and match the dimensions to that use. Reviewing the number of card slots, compartments and overall silhouette will help you select a piece that fits both your lifestyle and existing accessories.
