Talking about clothing in Spanish is one of the practical ways you can put your knowledge of Spanish to use. "Camisa" is Spanish for "shirt." When referring to a person's article of clothing, it is usual to use a definite article rather than a possessive pronoun, much as is done with body parts. In other words, someone could refer to your shirt as la camisa (the shirt) rather than tu camisa (your shirt) if the meaning is still clear.
