Polka Dots with Pastel Overlay: Vector Phone Case Sticker Prompts

Create a series of clean, high-contrast vector designs for phone case stickers featuring polka dots with pastel overlays. Each design should have a pure white background, no shading or gradients, perfect for die-cut sticker formats. Incorporate various pastel color combinations, dot sizes, arrangements, and overlay styles using placeholder text [e.g., ‘pastel_overlay_color’, ‘dot_size’, ‘dot_spacing’]. The designs should emphasize simplicity, clarity, and vibrancy, with sharp outlines and flat color fills, ready for high-quality printing.
