The Frankie Bikini bottoms are a comfortable high rise, high waist style that give you complete confidence going in and out of the water. Always double lined, UPF 50+ and made with plastics found in our oceans. Pair these gorgeous bottoms with our Frankie, Penelope or Chelsea Bikini Tops. Zoe is wearing an XS as she prefers a cheeky bottom style. Go with your original sizing for the full coverage look. All our swimwear does expand half a size in the water due to its 4 way stretch. They will return to size once dry. This is to ensure they mould to your body shape perfectly. We do recommend a close fit for this reason. Bombshell Bay take sustainability seriously.
