A t shirt is an essential in every kind of weather. During the hot months of spring and summer, speak your mind one with one with a cute quote on it. For hot days, choose a cotton t shirt that will keep you cool. Bring back the hippie era by pairing it with worn jeans or hipster pants to create that grunge look. Tumblr has a great showcase of how to work all kinds of t shirts to be casual, casual chic or semi-formal by layering with a blazer on top. T shirts are very versatile and will never go out of style.
