OKay, again, was probably covered, but just want to make sure it's understood. About getting Emma Frost to like you, even if you raise any of her Stats (Love, Obedience, Inhibitions, etc.) to max, in order for any person to wear the "custom" clothes or even have her naked in public, it required 3 parts...
1.) Max the stats out...
2.) You have to get her to love you (Girlfriend status, although much easier when she is willing to be your slave or willing to be your girl, although some don't require getting to this, if your stats are maxed, you can get her undressed pretty much right away, although I usually get them in public with max stats and ask her to undress anyways, and that usually works)
3.) Have to get them to do lewd acts while in a public place and you get a message that says "She's become a bit of an Exhibitionist..."
However when it comes to the White Queen (Emma Frost), she has to be willing to be seen with you in public as well as willing to be your girl in public. You have to remember, she's a teacher, and she makes it known to you that you will have to try super hard to get her to be willing to do things for you, just to be seen in public with you. Now, once you managed to get her to love you to be in public, and while you are in a public location, first ask her to undress, then get her to do something lewd like stripping or dancing, or just make out. Now, when the "crowd" comment appears, just say "Just Continue" (Or some comment like that) and you want to keep doing this until you get a message that says "She's become a bit of an exhibitionist...". Once you see this with Emma, then you can get her completely naked in public. Once you can get past the part where she doesn't mind being with you, and you accomplished the above 2 parts, then and only then will Emma be willing to be naked in public. She will also have the power to change Xavior's mind should you be caught by him, then you can choose the third option, some like "Psi Attack" (I forget the exact selection, but it's something like that). This only appears when you get her Love, Obedience, and possibly her Inhibitions high enough and she's already your girlfriend/sweetheart/slave.
I apologize again if this was covered, I did read as much as I could and didn't see anyone covering this, so I am hoping this will help.
