Evidence of the very first clothing is mostly indirect. Almost all of what we know about early clothes is based on conjecture and assumption. It is impossible to say when humans first started wearing garments. Based on the cave drawings, carved figures and other such evidences including remnants and traces of very early cloths, the archeologists suggested that humans may have begun wearing clothing between 100,000 to 500,000 years ago. Neanderthal man, who lived between 200,000 B.C.E. to 30,000 B.C.E., learnt to use the hides of the animals they hunted to keep themselves warm and dry, referred as the first known person to fabricate clothing. It's also possible that clothes were designed for other functions at first, such as adornment, worship, or prestige, and were later discovered to be useful as well. This paper includes the investigation about need and psychology behind the origin of clothing through some fundamental theories of clothing and their applications to perform very specific functions. This research aims to reveal fashion concepts, as well as the path from prehistoric man's clothing demands to present fashion trends. Furthermore, it lays the foundation for those who are keen to learn fashion by starting a discussion on why people wear clothes so that the readers/ fashion graduates and professionals can recognize the motivations behind the desires of individuals in order to design and construct clothes in creative ways to maximize wearer’s satisfaction level.
