She goes along with it to not blow her cover, but it turns out to be for a nude show where she has to stand on display as people walk around and take photos. After standing there for awhile the real model arrives and the event coordinator realizes she's not part one of the show and she has to make her escape in the nude.
Alternatively, put a twist on it where security knows she's a spy but don't want to scare her off and so they "assume" she's there for an actress interview. She goes along with it, but the interview gets more and more demanding getting her to strip off and stand in embarrassing poses, eventually leading her into another rooms with other people to further her humiliation.
Whenever she tries to protest, they start acting like maybe she doesn't belong so she keeps going with it, thinking she might be able to get away with it, but it's already over for her.
>"Okay let's get started, remove your clothes">"W-what I thought this was for a regular interview, I can't do that!">"What do you mean you're not going to take off your clothes? Your agent clearly said you're fine doing nude scenes and that you have done them dozens of times before! That's what this interview is for! hmm but you look a little different than what I remember of your headshots maybe I should pull them up-">"O-o-okay, I was just mixed up, my apologies, please forget that" *starts undressing*
