AUS Size small Underwire free, soft, stretchy bralette with elastic trimming. Recycled polyester, spandex * 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. We recommend purchasing darker patterned prints if wearing them for swim. Like any swim attire, we recommend a rinse after salt water or chlorine and to avoid abrasive surfaces.
