Recs for how to turn people clothes into BAB clothes?

Hi all! Does anyone know of an Etsy seller or company or anything where you can send them your own clothes (like an adult sized t-shirt and pair of shorts) and they can use that fabric to make a BAB t-shirt and shorts? I have 2 favorite tshirts and a favorite pair of shorts that are falling apart and I want to have turned into clothes for my bear. Any recs would be appreciated! I am inept with sewing so you can skip DIY recs lol.
