Hippy costume ideas please!

[Posey]

Dd is 10 and going to a hippy party!
She has long hair which I'll crimp and braid and bung flowers in.
Any other ideas? Minimal time and expense please as both are in short supply!

TIA

Have you got a plain tshirt you could tie dye?

also baggy jeans/flared or a long flared gypsy style skirt.

Use facepaints/make-up to paint a CND symbol and some flowers on her cheeks.
