It also highly depends on the sport. Typically anything with racing will try to be "streamlined" so there is less resistance, and you'd be surprised how much resistance a piece of fabric will cause with these amazing athletes (at their super-human speeds, it's crazy).

However, for sports like volleyball, and track&amp;field (for example) it's all about "looking at pretty girls"

It’s kinda funny to read through these comments as a swimmer. FINA (the governing body for swimming) has some very strict uniform requirements, and the male coverage is much less than the female coverage. And both genders would happily cover more if they could. Males can cover waist to knees, and women can cover the neck to knees. With modern fabrics and technology, the more coverage you have, the faster you go. Full body suits were allowed in the 2008 Olympics. Some people think that some of the records set there will never be beaten because of the swimsuits.
