Well, the title sounds silly. Obviously, most clothing is gluten-free, however many of the cookies and bread still seem to taste like an old shoe!
All jokes aside, there are a lot of websites that carry shirts and other apparel with cute gluten-free sayings.
Here are a list of gluten free clothing sites. Many also contain novelty items such as keychains, mugs and artwork. Check out the The Gluten Free Travel Site for their zany shorts that say, “These Buns Are Gluten Free.” A great gift for the newly diagnosed celiac!
