Create a navy blue and white retro vector illustration of a strikingly beautiful 1950s woman with glamorous big styled hair held by a patterned headscarf, wearing a pearl necklace and sleeveless top, holding up a large kitchen knife with gleeful abandon. Her mouth is wide open laughing with bright mischievous eyes. Scatter six-pointed sparkle stars throughout. Add bold arched text reading "COMPLETELY" above and "UNHINGED" in very large heavy block letters below. Style: high-contrast flat navy blue graphic, bold linework, no gradients, pale gray background.
