Navy gingham. Super comfy, versatile high waisted style bottoms with elastic trimming. New with tags. Recycled polyester spandex with bamboo gusset. * Bimbys are not lined/as thick as the common swim attire, but due to the quick dry nature of the material, Bimbys are swim-friendly and commonly used in water. See final photo for size guide. Bought from Australian retail site. See matching Bimby and Roy NETE bralette top in my closet.
