a two-piece bikini rendered entirely as a rough hand-drawn colored-pen illustration, deliberately messy and amateur-looking rather than polished digital art, visually constructed from many thin multicolored pen strokes scribbled repeatedly back and forth across the bikini, mostly short horizontal strokes, overlapping uneven lines, inconsistent spacing, irregular stroke lengths, occasional crossed lines, imperfect edges, visible gaps between some strokes, uneven color density, loose scribbled boundaries, pastel pink, cyan, turquoise, yellow, lavender, mint green and coral pen lines, each individual pen stroke clearly visible, like someone quickly scribbled the bikini onto a photograph afterward using several fine-tip colored pens, intentionally rough and casual, no smooth fill, no clean cel shading, no realistic textile texture, no rainbow fabric, no striped fabric, unmistakably hand-scribbled 2D pen artwork
