Her outfit is a calming blend of sky blue and glacier white with soft, glossy accents, reflecting the familiar gradient from the early XP era. Her hair is a long, ribbon-like ponytail tied with a pale blue band, and a tiny XP window emblem sits on her chest as a subtle, tasteful motif. The figure features precise sculpting on folds of fabric and hair strands, bringing a sense of movement even when stationary. The paint app uses clean lines, with minimal shading that emphasizes a friendly, approachable character. The base includes glyphs and a soft glow to echo classic desktop themes without overwhelming the figure.
