Williamson-Dickie Manufacturing Company is the official name for this popular clothing brand. Originally meant (and still used) for work environments, such as for a mechanic, however, today many people of different believes and backgrounds are clad in Dickies, such as kids in full dickies outfits (at school for example). Also, it is very popular in schools in the Philadelphia region of Pennsylvania.
