STYLE: bold cel-shaded 80s disco cartoon, thick black outlines, flat saturated fills, one hard shadow tone, crisp white glossy highlights; match the base's line weight exactly. Colours from the fabric, never the base's brown skin.

POSE: three-quarter-right, head and shoulders, body turned to her left, chin up; her right-side shoulder (viewer's right) is raised toward camera: its top outline runs from about (520,860) up to (700,840) and down to (900,1024); the left shoulder (viewer's left) slopes from about (410,905) out to (110,1000) and off the bottom-left edge.

GARMENT: 12 complete disco tops WORN on her body, 100% alpha (fully opaque) over every body pixel below the neckline: no translucency, no thin strip. It must cover BOTH shoulders entirely, following their outlines, and run to the bottom edge y=1024 across x=11..1014 wherever her body is; the raised right shoulder becomes a fabric sleeve drawn in front, overlapping the right side of the neck.

NECK: neckline wraps the neck base at y≈900 between x=410 and x=625; leave the throat and neck between those x values above the collar transparent; never paint the inside, back wall or lining of the collar, never fill the neck hole. Wide pointed collars spread open flat over the collarbones/shoulder, points aimed down-outward; open-collar shirts may show a small transparent V at the front only.

Keep clear of the hoop earrings (x 300..385 and 635..725, y 630..815) and the face; nothing above y=830 except collar tips at the neck. No jewellery, chains or pendants on any garment.

VARIANTS (all clearly different): 01 white satin Saturday Night Fever shirt, huge pointed collar; 02 black satin shirt, wide collar; 03 burnt-orange and brown geometric 70s print shirt; 04 gold sequinned long-sleeve top; 05 silver sequinned top; 06 hot-pink satin wrap blouse; 07 teal satin wrap blouse; 08 purple-and-mustard paisley shirt; 09 scarlet satin shirt, wide collar; 10 rainbow-stripe disco shirt; 11 electric-blue lamé wrap blouse; 12 leopard-print satin shirt with wide collar.
