Panache Gingham Paloma Full Cup Swimsuit
Sky Blue

At J cup only genuine bra-sized construction works in a swimsuit. The list of brands that deliver it is short, and we would rather range the few that do than pad the page with styles that will not hold.

What to look for at J cup

Long channelled underwires that clear the side tissue, firm cup fabric that does not relax when wet, and wide adjustable straps that carry the weight without digging.
