Getting dressed, far from being an act devoid of intent, is the construction of a message by the individual with a social function as an externalization of his inner self that allows him even to get by without the use of words to express that inner self. With a qualitative approach, this article discusses the use of the T-shirt, which presents a late awakening in the history of wardrobe design where its attributes, texture and color give it an advantage over other pieces of clothing in its role as a channel for the expression of the individual. This is how it is possible to build a close relationship with the corporeality of the subject which facilitates the materialization of their speeches through verbal and non-verbal codes. The study allowed applying a semi structured questionnaire to experts in fashion. Elements related to the occasion for using T-shirts and how they condition the transmission of the message, the factors that determine their validity, the T-shirts consumers profile and their motivators when wearing them, were found among the main results.
