In her home, she wears a short-sleeved V-neck white T-shirt with a hot pink T-shirt with short sleeves which are slightly longer. Yuuko's outfits are typically tomboyish in nature, though she will rarely wear a skirt or dress.
Her school uniform consists a pale beige sailor top-like blazer with thin white stripes in the middle and at the end of the blazer with a curved white sailor collar that has a thick pale red stripe nearly around the edges and short pale red bow with a chest pocket at the right side. In the warmer months, Yuuko's school uniform consists of a white top with a blue tie and blue skirt.
In a bedtime, Yuuko wears a yellow pajama.
