competition swimsuit
A type of performance-optimized one-piece swimsuit that is commonly worn in swimming meets and competitions. They are different from more casual one-pieces in having a racerback as opposed to "backless" ones, and they appear to have a slimming effect, allowing for easier movement through the water. Real-world designs also tend not to emphasize cleavage, since having the chest area exposed is not optimal for hydrodynamics.
There are also unisexual competition swimsuits that resemble bodysuits and wetsuits and cover either the legs or the thighs (like bike shorts). These unisex suits have become standard wear in international swimming competitions for both sexes (especially for women) in recent decades as a modesty measure, something yet to be applied in diving and synchronized swimming events.
Some of the following companies' logos are apparent in such swimsuits:
