People often get attached to certain clothing: old jeans, favorite shoes, sunglasses or shirts. I have one article of clothing I really love and it's a shirt. It is classified as a "baselayer", which is clothing designed to be worn under other clothing to help provided extra moisture wicking and warmth. Since I live in Florida, I usually just wear it as outer wear in a looser size. My favorite shirt is the Patagonia Capilene T-Shirt.
