A great anniversary gift for your wife who likes swing/big band could be to surprise her with tickets to a local swing/big band concert or even plan a weekend trip to attend a larger swing/big band festival. You could also gift her a vinyl record of her favorite swing/big band artist or album, along with a record player if she doesn't already have one. Additionally, you could create a personalized playlist of swing/big band songs specifically for her and get her a new set of headphones or a portable speaker to listen to it on. If she's interested in learning to dance, you could sign both of you up for a swing dance class as a fun and interactive gift.
Or you can get her a star map with the date of your anniversary.
