Young Reddish Blonde Girl Undresses Her Golden Swimsuit

Both men and women may sometimes wear swimsuits covering more of the body when swimming in cold water (wetsuit and dry suit). In colder temperatures, the swimwear is needed to conserve body heat and protect the body core from hypothermia.
Competitive swimwear
Some swimsuits are designed specifically for swimming competitions where they may be constructed of a special low resistance fabric. They reduce skin drag, and can resemble unitards. For some kinds of swimming and diving, special bodysuits called diveskins are worn. These suits are made from spandex and provide little thermal protection, but they do protect the skin from stings and abrasion. Most competitive swimmers also wear special swimsuits including partial and full bodysuits, racerback styles, jammers and racing briefs to assist their glide through the water thus gaining a speed advantage (competitive swimwear).
