Serena began the series wearing simple black sneakers with a pink Pokeball design on the heel. As the series progressed, she gained more confidence and decided to change her look. She swapped out the sneakers for calf-high tight brown boots to help show her newfound inner strength. Serena is almost never seen without thigh-high black stockings covering her legs.
During pokemon showcases, she wears several different shoes, including knee-high green boots and stylish pink flats.
