Generate a half-body portrait in a glamorous vintage pin-up style, capturing the idealized aesthetic of the 1940s. The subject should be depicted with perfectly sculpted victory rolls hairstyle and bold red lipstick. She should be wearing a classic 1940s-style fitted navy blue dress adorned with white polka dots. Ensure the lighting is soft and warm, characteristic of studio photography from the era, with a shallow depth of field to keep the focus primarily on the subject. The background should be subtly themed to evoke the 1940s without being distracting.
