This princess has been invited to a cocktail party and as this is an important social event, she needs to make a good impression. A golden outfit is just what she needs, so you could be her fashion consultant. You need to decide between a casual chic or an elegant look. Why not create both looks for her, decide which suits her the best, and which one is more proper for this event. Mix and match different clothing pieces from her wardrobe and create both looks. If you still can't decide, you can mix both styles, giving her a touch of casual and a touch of elegance.
