I was going to suggest a waitscoat too but for tomboyishness Id go for some fitted trousers.
Also obvious makeup like red lipstick to emphasise a sense of feminity though.

Other than that I cant be very helpful :frown:
I'd have said some shorts, a sparkly top but a tophat and tails!

I would go for long boots and a long puffy skirt to about the mid calf. with a blouse and a waistcoat. I agree with louisedotcom about the red lipstick.

All of the above ideas are good, place a pair of braces perhaps.
