UK 50JJ is the same as US 50N, so this page brings together bras for a very full bust on a wider band. At this size, a band with wide wings and several hooks carries most of the support, the wires should sit back far enough to surround all your breast tissue, and the straps should never be left doing all the work. If you are unsure whether UK 50JJ is the right starting point, use our Bra Size Chart before choosing your next style.
