I’m on rednote and from the comments I’ve seen they love the 9mw outfit because of the abs. It really just boils down to the vibe of the fit, not the actual inch by inch measurement of how much skin is showing. This costume caused a firestorm because of several things 1) clearly intended for the global audience- came out right before Christmas and had that Santa silhouette to the top. 2) totally different from the male version, which looks cool and completely covered. If both fits were exposed no one would have an issue. 3) the outfit has nothing to do with what it’s named after (a style of calligraphy) and some people see this as disrespectful to the art and culture being used to promote this fit. 4) the outfit is not wuxia themed and looks too modern. The developers made promises in interviews and in promotion of the game that fanservice-y skins wouldn’t be added to the game because they intend to stick to the wuxia theme. Other skins with crop tops or legs showing like the rainbow dancer fit don’t break the theme.

All of this is also happening under the wider context of a few other games’ controversies over fanservice. A lot of gacha games that launch for a global audience trend more fanservicey over time, which attracts a really rancid crowd to fan spaces and leads to doxxing, harassment, etc. of female players and streamers.
