How about getting her a custom Sims-themed portrait or painting? You could have someone paint or draw her as a Sim character, or even get a custom-made Sims-themed picture frame to go along with it. Another idea could be to create a Sims-inspired date night where you both play the game together, and perhaps even create Sims characters of yourselves. Additionally, there are many Sims-themed merchandise available in the market like T-shirts, mugs, keychains, and phone cases which could be a great addition to her collection.
Or you can get her a star map with the date of your first kiss.
