I couldn't seem to find a site that would do matching, custom T-shirts for all sizes. I ended up buying some custom-made iron-on decals (with Disney mouse silhouettes, our names, etc.) from "MissMorgan" on Etsy, although there are several Etsy sellers who do them. I bought T-shirts on clearance from Old Navy and ironed the decals on, myself. I think the total investment was $7-$10 per shirt. Not only did the shirts look terrific, but that was back in 2012 and the shirts have withstood multiple washings and still look great.
