Waist beads are a traditional African accessory that consist of small glass beads on a string or wire worn around the waist or hips. Waist beads have been worn for centuries by women in many West African cultures. In more recent years they’ve gained popularity among women in the West. They’re also referred to as belly beads, waistline beads, or beaded waist chains.In Ghana, Nigeria, Senegal, and other West African countries, waist beads are a symbol of femininity, fertility, sensuality, and spiritual well-being. Today, in both Africa and the United States, women use waist beads for aesthetic and practical purposes. (Heathline)
