Willow appears to be around the age of 18 but her actual age is not known; she long red hair, brown eyes with fair skin that at times seems to sparkle in the right kind of light. As long as there has been a circus Willow has been there. She typically wears long flowing dresses, made of silk, Willow has never been known to wear shoes, always seen barefoot.
Willow in her fairy form is interesting she shrinks down in size no bigger than your thumb, and grows wings, that mimic the color of fall leaves.
