In the later seasons of the show, Olivia's style had fully matured, reflecting her artistic and creative personality. Her fashion choices became more sophisticated, with a focus on statement pieces, bright colors, and playful patterns. Her hair was often styled in a more polished, sleek look, and her makeup was more defined, accentuating her features. A memorable look from this period includes her outfit in the episode "Graduation Day" (Season 5, Episode 13), where she wore a stunning, emerald green dress with a pair of neutral heels and a matching clutch.
