A 40HH pairs a wider UK underband with a very high cup volume. At this size, the band provides the primary source of support, while the cups are responsible for managing volume and maintaining shape.
In a 40HH bra, stable construction across the band, cups, and wings helps distribute weight evenly across the torso. Designs that prioritise anchoring and containment support comfort during extended daily wear.
Before selecting a style, confirm your measurements using the Bra Size Calculator. Our Bra Fitting Advice explains key fit checks, while the Bra Size Converter can assist when comparing sizes between brands.
