A friend at work recommended Jen Wang's The Prince and the Dressmaker to me. In it, Frances, a dressmaker working under someone (lol it reminded me a lot of The Gown in that way) makes someone exactly the sort of dress they want, to the consternation of her boss. When he's reprimanding her, a man comes looking to hire her for a mysterious client, who Frances discovers is the Crown Prince Sebastian of Belgium. Prince Sebastian enjoys dressing in women's dresses and wants Frances to design dresses that everyone will notice and remember. Prince Sebastian starts going out on the town dressed as the Lady Crystallia, and Frances' dresses are indeed getting noticed, to the point where the pair worry people will put two and two together and figure out just who Lady Crystallia really is.
I loved this book. Wang's art style is perfect (and I'm glad she decided to make them teenagers - she included a sample page of the pair as adults and the art just didn't have the same charm that the final version has). I also loved how Sebastian's parents supported him in the end, especially his father; I wish that everyone could be as lucky as Sebastian was in this regard.
All in all, The Prince and the Dressmaker is a delightful story about being true to yourself and your friends. I very much recommend it!
