What if multiple companions offer you their personal fashion advice
? Like Viv and Leliana for example? And you can choose one of them to dress you for the party?
Leliana: You're...not going to show up like that are you? No, this won't do. Inquisitor,I insist on taking you shopping. We'll find you a nice dress, some new shoes...we'll have to do something about that hair as well.
Inquisitor: -...um, I appreciate that Leliana but -Wait, what's wrong with my hair? -Now hold on a minute!
Viv: That's sweet dear. But if anyone is offering the Inquisitor fashion advice, clearly, it should be me. I have mastered the art of making an entrance , no one at this ball will be able to keep their eyes off you once I've worked my magic.
Cass: *rolls eyes* Doesn't that defeat the entire purpose of the Inquisitor infiltrating this ball? The less people noticing her the better.
Leliana: It's a masquerade, she'll be wearing a mask the entire time. Still, there's no reason why she can't look her best as well.
Viv: Exactly. Inquisitor, who do you wish to help prepare you for tonight's ball?
Inquisitor: - Ok Leliana, why don't you help me pick something -Vivienne this is your department, what do you suggest? -Thanks, but I'll pick something out myself
Something like that. And depending on who you choose to help you reflects how people respond to your attire at the party. But there should totally be an oddball choice like picking The Iron Bull to help you or something and it turns out they have really good or really bad taste in clothes XD
