During her time at Hope's Peak Academy, she wore the standard issued school uniform with a brown vest over her white dress shirt. She also wore a brown headband stylized with four-leaf clover on the right side of her hair, black thigh highs, and brown loafers. Her hair was a more golden shade of blonde, also lacked the braid crown and was considerably longer, flowing to ankle length. Because of her upbringing, Sonia can be rather naïve and her general behavior can make her appear a bit ditzy.
