Have you ever dropped sauce on your shirt while you were enjoying a delicious hot dog at a backyard barbecue? Of course you have! And if you haven't then you should fire up the grill.
Now when you're wearing this shirt and you have a little drip or two it's okay. Just tell people "Oh, no, it's part of the design."
Treat your shirt like a page out of a coloring book and color in the areas with your favorite sauces! Outside of the lines is encouraged and each time you wear it it's like a new shirt!
