A great anniversary gift idea for your girlfriend who loves swing/big band could be to take her to a live performance of a swing/big band orchestra. You can also consider buying her a vinyl record or CD of her favorite swing/big band songs or even a classic swing dance video to watch together. Additionally, you can purchase a vintage-inspired outfit for her to wear to the performance or a pair of fun swing dance shoes to wear while dancing. Another thoughtful gift option could be to create a scrapbook or photo album of your favorite memories together, including pictures of any swing dance events you've attended.
Or you can get her a star map with the date of your anniversary.
