Skimpy swimsuits are a popular choice for beachwear, and typically consist of thongs (6 letters), speedos (7 letters) and bikinis (7 letters). Thongs are a type of swimsuit that covers the wearer's buttocks, while speedos are a type of tight-fitting swimsuit that covers the wearer's groin area. Bikinis are two-piece swimsuits that cover the wearer's breasts and groin area. All three of these types of swimsuits are considered to be skimpy, as they leave much of the body exposed.
