Because at the same time, if they make a character’s clothing too revealing, they’ll have their wrists slapped by the government censors. I used to play Genshin Impact, and Hoyo got slapped during that time:

Gacha games (especially these days) are usually more censored on Chinese servers than on global ones to avoid government interest. That’s why you can have long running titles like Azur Lane being kinda crazy with their skins without getting into trouble while other ones (Snowbreak) crash and burn because their devs felt a little too comfortable skirting the rules.
Not saying whether any of that is good or bad but CN servers do tend to err on the side of caution with their designs.
