Remember, the stats of a character are between their character model name, and the character's name.
So for instance, if you want to edit Christy, it's between GN_SexyGirl, and N_Christy.
Or for Angie, it's the stuff between GN_AsianGirl and N_Angie.
One thing to note though: You'll notice that there's GN_SexyGirl and then GN_SexyGirl_W. The second part indicates their winter uniform.
And, in a separate part of the ide file, they have different models. Like for example, GN_SexyGirl_CH spawns Christy in her cheerleader uniform. Or, GN_SexyGirl_UW spawns her in her pajamas.
