One great gift idea for your husband who is interested in sustainable fashion could be a gift card to a sustainable fashion brand. This would allow him to choose his own stylish and eco-friendly clothing pieces, or even shoes or accessories, which would suit his personal style and fashion preferences. Another idea could be to find a way to incorporate sustainability into his current wardrobe, for example, by gifting him a sturdy and eco-friendly canvas tote bag or a reusable water bottle, both of which would make for practical and environmentally-friendly presents. If he's into DIY, you could also help him in finding tutorials online for making upcycled accessories or clothes.
Or you can get him a star map with an important date you share.
