Rebecca Latham. All growing up, you're taught to always be yourself. But what if you could be a.. ..POLAR BEAR?! This Animal World design is printed on a 100% polyester toddler t-shirt, and features the words, "Always be yourself, unless you can be a Polar Bear then always be a Polar Bear" with a polar bear graphic. The dye sublimation process creates slight imperfections that are unique to each garment.
