How about a sustainable fashion subscription service? Several companies offer monthly boxes of ethically-made and sustainable clothing items, personalized to your wife's style preferences. Alternatively, you could purchase an item or two from a sustainable fashion brand that she likes - some popular options include Everlane, Reformation, and Patagonia. You could also consider a gift card to a sustainable fashion boutique or website, so she can choose items for herself. Finally, you could give her a reusable tote bag or water bottle made from eco-friendly materials, which are both useful and sustainable.
Or you can get her a star map with an important date you share.
