These days, swim shorts should definitely be above your knee, but below where a reasonable pocket would end. The exact length is a matter of your height, leg length and your comfort/preference. Some guys like it a little shorter and others not so much. For pool and beach wear, midthigh or a little higher is the look for now.
Bodysuit is a comfortable, elegant and multi-functional piece of women's underwear. The famous fashion designer Donna Karan has invented it. The style of a basic bodysuit is similar to a one-piece swimsuit and a leotard, and its purpose is the link between clothing and underwear. In general, textile bodysuits include expandable fiber such as spandex for a better fit to the shape of the body.
