Sometimes our favorite wardrobe pieces might not be the fancy leather jacket we got on our last trip to Europe, or our denim-washed designer skinny jeans we spent months saving to buy. In fact, sometimes our favorite clothing piece can be something as simple as a t-shirt. But the truth is, that unlike any other piece of clothing, t-shirts work as a great way of self-expression. Through messages, images or pretty much any kind of design printed on them, they allow us to display our political or social views, promote a cause or simply reflect our creativity and personality, making them an essential must-have in our closets!
