UK 28GG is the same as US 28J, so this page brings together bras for a full bust on a very small band. At this size, a firm, narrow band does most of the anchoring, the cups should hold you fully, with no spilling at the neckline or sides, and the straps should stay put without digging in. If you are unsure whether UK 28GG is the right starting point, use our Bra Size Chart before choosing your next style.
