Bikini bottoms, also known as the lower garment of a bikini swimsuit, are designed to provide coverage and support for the lower body while engaging in water-based activities. They come in various fabrics, styles, and designs, offering options to suit different body types and preferences. The type of fabric used can influence comfort, durability, and appearance, while the style and design can flatter different body shapes and enhance the overall aesthetic. Coordinating tops and accessories can complement the bikini bottom, completing the outfit for beach or poolside fashion.
