Y2K Kawaii Pastel Portrait

Create a square close-up Y2K kawaii studio portrait of a young woman with {argument name="hair color" default="dark black-brown"} slightly messy shoulder-length hair and wispy bangs, looking upward to the side with glossy eyes and a playful duck-face pout. She is centered against a smooth pastel lavender background with soft even lighting and a dreamy beauty-editorial finish. Style her with a pale powder-blue knitted beanie that has two rounded bear-ear bumps, a light blue ribbed camisole with white trim and a tiny bow at the neckline, a silver chain necklace with a small heart charm, and long fuzzy fingerless arm warmers with horizontal pastel rainbow stripes in pink, blue, purple, yellow, and peach. Pose both hands raised symmetrically, index fingers pressing gently into her cheeks. Add small pastel star stickers on both cheeks, about 16 total, scattered in pink, blue, yellow, and lavender. Makeup should be soft and glossy: pink blush, subtle shimmer eyeshadow, defined lashes, natural dewy skin, and shiny pink lips. Use a shallow depth of field, crisp facial detail, soft film-like color grading, high-resolution fashion photography, nostalgic early-2000s Japanese idol portrait mood, cute and polished, no text or watermark.
