Why so Serious? This Batman t-shirt features the classic line from The Dark Knight in an edge to edge design. This 100% polyester shirt is available in adult sizes. Please note that this t-shirt uses a dye sublimation print process which creates slight imperfections that are unique to each garment. While the manufacturer takes every step to minimize these imperfections, they cannot be eliminated completely. Some examples of what you might see include folds with white showing through at the arm pits, sleeves, shoulders and sides, and white seams at the arms, shoulders and sides.
