Weight 0.9 seems to be the sweet spot with this one.
Note: Personally I would say her skin tone seems to be quite inconsistent even in her official artworks, she is sometimes depicted with either pale white or a more normal skin tone. You can still use "colored skin", "white skin" and "pale skin" tags as helpers with increased weight (1.4 at most), I noticed it works best in her kunoichi outfit (because the pictures for that outfit dataset mostly had her in with pale skin). I could have just edited the pictures in the dataset for her other outfits before training but I rather used them as is directly from oficial artworks and in-game CGI, if it's an issue for you, it can be fixed by user preference by increasing skin color tag weights.
Her red swimsuit outfit only has 4 pictures I could track, Had to do some sorcery to get it working to a decent state, expect only a few small inconsistencies though.
