A bra consists of several key components that work together to provide support and shape. The main parts include the cups, which hold and shape the breasts, and the band, which wraps around the torso and provides stability. The straps connect the cups to the band and help lift the breasts, while the underwire (if present) offers additional support by running along the bottom of the cups. Other important elements include the closure, typically found at the back, which allows for easy wear and adjustment, and the padding, which can enhance the shape and size of the breasts. Each component plays a crucial role in the overall fit and comfort of the bra.
