Tism-O is a neurodivergent humor T-shirt built around the internet shorthand tism and the kind of retro-label parody that looks almost respectable at first glance. It is self-referential, deadpan, and designed for people who prefer autism humor that feels more like an inside joke than an inspirational poster.

Shirt details: Bella+Canvas unisex jersey tee with Airlume combed and ring-spun cotton, retail fit, side-seamed construction, and pre-shrunk fabric. Fiber content may vary by color. Printed to order and shipped from Detroit, Michigan.
