Nope! You can customize the following:
Pictured above is a Bella + Canvas 3001 Unisex Staple T-Shirt in True Royal, but if you want a hoodie instead you can also use the Gildan 18500 Unisex Heavy Blend Hoodie. Or you could use something else from Printful's catalog entirely!
Click on the links to the shirt/hoodie models in the question above to see how much money you'll probably be paying! (Be sure to also check the cost of shipping to your region, and factor in any applicable taxes. You will also need to add another $6.50 USD for all embroidered designs because Printful charges a digitization fee for them. Sigh.)
You can use a different shirt printer if Printful costs too much, especially if you're not from the US or EU. Although I have no idea who else would offer embroidery for a single shirt/hoodie...
