Evolution of suits over the years

[PSDave]

When the 100% nylon suits were worn for competitive swimming there was a different suit made for diving. It was made out of something similar to spandex and was very high over the waist. (usually about 8" sides) It fit very tight and didn't offer water resistance when entering the water. The nylon suits fit much lower and briefer. Though worn tight, the nylon and lower fit offered more chance of a Wardrobe Malfunction when entering the water on a dive. When the nylon/lycra blend was perfected more the suits became interchangeable.
