She is portrayed by Debora Villa.
Nina often wears a navy blue dress with a yellow collar, pocket, sleeve ends and buttons and her hair tied back with a yellow bow/scrunch. On an odd occasion, she will wear a royal blue dress as apposed to her navy blue dress, with the yellow sowing staying. She was also seen out of school once, where she was shown to have quite an eccentric style, much like her personality, wearing a pink and black polka dot dress with a bere in stripes of the same colours.
In season 2, Nina's style has not changed. She continues to wear her navy blue dress with yellow sowing, and a yellow scrunch.
In season 3, Nina's clothes change to a more sophisticated look. She wears her normal attire for a few episodes, but later switches to a navy blue blazer with a lighter shade of yellow sowing with a white dress underneath. Nina's style outside of Melsher Institute is the same, however it is less loud and more subtle.
Before the Show
