When Nintendo and Sega co-published Mario and Sonic at the London 2012 Olympic Games, we had female characters wearing proper gymnastics and swimming attires. One thing unusual about the female gymnastics attire is that it is also the swimming attire as well. This logic contradicts the fact that gymnastics leotards are not suitable for swimming.
If you want to know why the ice skater is not wearing a skirt, this was because when I went on a cruise ship, I saw an ice skating performance, in which a female ice skater took off her skirt. However, this seems acceptable because that's what ice skating leotards with detachable skirts are made for.
This comic is just made for the idea of what a female bodysuit specially designed for gymnastics, swimming and ice skating would look like.
