  Standard everyday clothing is usually impractical for swimming and is unsafe under some circumstances. Most cultures today expect swimmers to wear swimsuits.
  
  Men's swimsuits commonly resemble shorts, or briefs. Men's casual swimsuits (for example, boardshorts) are rarely skintight, unlike competitive swimwear, like jammers or diveskins. In most cases, boys and men swim with their upper body exposed, except in countries where custom or law prohibits it in a public setting, or for practical reasons such as sun protection.
  
  Modern women's swimsuits are generally skintight, covering the pubic region and the breasts (See bikini). Women's swimwear may also cover the midriff as well. Women's swimwear is often a fashion statement, and whether it is modest or not is a subject of debate by many groups, religious and secular.
  
  Competitive swimwear is built so that the wearer can swim faster and more efficiently. Modern competitive swimwear is skintight and lightweight. There are many kinds of competitive swimwear for each gender. It is used in aquatic competitions, such as water polo, swim racing, diving, and rowing.
  
  Wetsuits provide both thermal insulation and flotation. Many swimmers lack buoyancy in the leg. The wetsuit provides additional volume at a lower density and therefore improves buoyancy and trim while swimming. It provides insulation between the skin and water which reduces heat loss. The wetsuit is the usual choice for those who swim in cold water for long periods of time, as it reduces susceptibility to hypothermia.
  
  Some people also choose to wear no clothing while swimming. In some European countries public pools allow clothes-free swimming and many countries have beaches where one can swim naked. It is legal to swim naked in the sea at all UK beaches. It was common for males to swim naked in a public setting up to the early 20th century. Today, swimming naked can be a rebellious activity or merely a casual one.
