She also wears a green knee-length skirt, white socks, and black and white tennis shoes. She also wears a green headband for her hair.

At night, her bedtime outfit consists of a pale pink nightgown with long, puffy sleeves, frills decorating the collar and wrists, and pale pink slippers. She also wears a pink headband for her hair.
