Clothes for Plushies?

where do y'all get clothes for your plushies?? I got this shadow the hedgehog plush from target that's about 21 inch length wise and moderately thin. He is my whole life and I've been wanting to dress him in like a shirt or somethung but I am unsure of where to find clothes in general for dolls/plushies. I just use glasses to dress him in a way 😭. Anything would help! thank you! this is him btw!! :3
