King Knight's not a king, but he's dressed the part. 

Now you can be a snappy dresser, too—Forward made sure Nina Matsumoto's official Shovel Knight design was only printed on the most opulent t-shirts from Canvas and District. (Unisex XS-4X are a poly-cotton blend, while all other sizes are 100% cotton.) 

Each one comes with a big bonus sticker, perfect for decorating your carriage, keep, crown, etc.
