Above her left eye, she wears a circular, light blue hair clip with a yellow lightning bolt in the center. She wears a short, hooded, light mustard yellow poncho that is split down the middle, held together with a thin, light red bow. The poncho has brown accents. Where the poncho splits, there is a brown moon icon on both the left and right.
