Young Blonde Girl Undresses From Her Blue Swimsuit

Men's swimsuits
• Swim briefs (also known as racing briefs, speedos, competition briefs, bathers, racer bathers) - Launched in at the 1956 Melbourne Olympics by Speedo, originally nylon swimwear in the same style as underwear briefs. Swim briefs are now often made of a nylon and spandex composite, while some longer lasting suits are made from polyester. The style varies from a full seat to thong or g-string. Most swim briefs have a beige or white lining on the inside front made of a similar fabric.
• Trunks - In the US, this describes a loose, mid-thigh style of swimwear, made of 100% polyester or 100% nylon fabric. They are usually shorter than boardshorts but longer than boxer shorts. They feature a polyester liner inside the shorts. Although trunks have been used as swimwear since the 1940s, their heyday was in 1990s when they were highly popularised thanks in part to TV shows like Baywatch. Today, they have been eclipsed by boardshorts among teenagers and young adults. They remain the norm with older age groups and young children.
In other cultures (particularly the UK) the term 'trunks' is used to describe swim briefs, although it has been increasingly common for any men's swimwear to be generically described as 'trunks'.
