The UK bra size chart is a widely used system for determining bra sizes based on two key measurements: band size (around the rib cage) and cup size (the difference between the bust and band measurements). This system uses specific methods for labeling cup sizes, making it unique compared to other countries. Understanding the UK bra size chart is essential for shopping locally or internationally, as the measurement systems can vary significantly. With clear labeling, the UK chart simplifies the process of finding a well-fitted bra.
