>>119508907It's something that's unique to animation that doesn't happen IRL. Animators can't (or usually don't) show any texture or dimension to a one-piece suit. Functionally, it's like the animator drew them nude, but with a color variation. With a bikini, the lines break up the form of the figure, making it clear they're wearing something. It's not so obvious with a one-piece suit.
That's why one-pieces are superior. You see more, while technically seeing less.
