  Title: History of competitive swimwear
  Passage: The history of competitive swimwear has been dominated by concerns over public nudity in the first half of the 20th century and by efforts to reduce water drag in the second half.  Those efforts initially lead swimmers to reduce the early sagging one-piece swimsuits down to briefs only.  With the development of new materials that tightly fit the body and offered lower resistance to water than human skin, this trend was reversed to a complete body coverage from heels to neck and wrists.  FINA banned full-body suits from competition effective from 1 January 2010, stating that it "wishes to recall the main and core principle is that swimming is a sport essentially based on the physical performance of the athlete".
