Nanally from Neverness To Everness video game in her swimsuit outfit. There is a lot less clothes clipping unlike the default outfit. The free-to-play game is available at nte.perfectworld.com , Steam, Epic Games Store and even Geforce NOW (if you want to play at max settings and don't have a gaming PC). You can play with Nanally in her swimsuit outfit within the game in the beach volleyball mini-game. It does have a learning curve though.
Disable mouse tracking if using with Mate Engine (available for free in github). Mate Engine will make her appear on your desktop like "Clippy" from Microsoft Office. Ah, maybe they named it "clippy" due to the clothes clipping issue. I am not sure why it is called that, instead of being "clothes going inside body" issue.
