Retro-futuristic pin-up astronaut with a 1950s aesthetic, posed in a playful and confident manner, wearing a tight white space suit with red accents, black gloves, and high-heeled boots. She holds a vintage, ray gun-style soda bottle emblazoned with "Nuka Cola," set against a vibrant red background with bold white stars and a circular emblem.
