What type of perfume should I get for this girl?

My cousin in turning 14.

I'm asking because she is a unique case. Until she was about 12, she was a HUGE tomboy. As in, people thought she was a boy all the time. She got special permission to play in the boys league. She wore suits to nice occasions and cut her hair short. She spoke and acted like a boy and eschewed girls. She was basically a butch (excuse my crudeness) preteen girl.

But now she's getting griller, she asked me to put makeup on her, she wears girls clothes and she owns 4 dresses that she loves. All are from Urban Outfitters - so that gives a sense of her style.

All her friends are boys, and she doesn't like or know ow to talk to girls besides me and my younger sisters.

I'm going on etsy and going to design a perfume for her, to make sure it will be something nice for her.

What type of body mist would be god for a girl coming into femininity, who likes shopping at Urban Outfitters (so a very West Coast, Bohemian style)? Spicy scent? What sort of top, middle and dry notes?

Thank you to everyone who answers!
