How about a ticket to a Katy Perry concert? You can surprise your girlfriend with this and it'll definitely be an enjoyable and memorable experience for her. If the concert isn't happening soon, you could give her a pair of noise-cancelling headphones and a playlist of her favorite Katy Perry songs. You could also gift her a Katy Perry T-shirt or hoodie. Or, if she's an avid reader, consider getting her Katy Perry's autobiography, "Katy Perry: Part of Me." It's a great way for her to learn more about her favorite artist and indulge in her passion for reading.
Or you can get her a star map with the date of your anniversary.
