A Visitor Stole His Heart (a selection fanfic) read the description.

Really?

It's the morning after Maxon got home from New Asia. They resolved the conflict so no more war! Anne brings me the newspaper to read. It reads Prince Maxon's fiance, America Singer, started out strong with the public. However now a decent bit of the public does not agree with her being a princess. She has a great personality but the way she dresses is a major step down from Queen Amberly. Yes, America is a popstar but still, after her concerts, she should change or even have a new look for her concerts. Something more royalty and not so trashy.
Oh my gosh is that what people really think of me. I take it and run to Maxon's room. He answers still in his pajamas. "What is it America?" I shove the paper at him and he reads it. "What are we going to do?" I ask frazzled. "Change your image." "And you have to act queenly. Carry yourself like one and talk like one, " he says. "Let me get dressed and then we'll go through your closet and look over some designs with your maids if you like, " Maxon offers. "Oh yes please!" I exclaim. He closes his door changes and comes back out. We go to my room and compile all of the clothes that I shouldn't wear anymore. When we are done with that we design some new dresses. Today we have a report so we are going to dress me up for that as well. Maxon id being so helpful.

So I change into a beautiful pink flowy dress.
