The main difference between a workout tank top for women and a camisole lies in their intended use and design. A workout tank top is specifically designed for physical activity, featuring moisture-wicking and breathable materials to keep you comfortable during workouts. It often has a sporty look and provides more coverage and support. On the other hand, a camisole is typically a more fashion-oriented garment, often worn as an undergarment or as part of a casual outfit, with thinner straps and lighter fabrics.
