We are technically animals but no other animal wears clothes. Why should we?
Once our ancient forefathers shed their body hair to adapt to their surroundings, we started to create clothes for ourselves because of many, many reasons.
Way back when, clothes not only kept you protected from the elements through regulating body temperature or keeping skin from being exposed to the sun, clothes also kept dirt off of our more sensitive areas and also kept us from becoming infested with insects. Much like the reason we started sleeping on mattresses raised off the ground, clothes' main attribute is healthiness.
Clothes were a must-have for winter weather. Our newly-hairless bodies didn't provide warmth during the harsh, cold conditions, so we started wearing animal furs and vegetation to keep in our body heat. Over time, cultures adapted their clothing to certain purposes, from pockets to scabbards, hats to masks, shoes to sandals, clothes not only were vital in survival, but also became a forefront in stylization. What we wore determined many, many different kinds of things; things such as wealth, class, occupation, bloodline, affiliations with groups, cities or kingdoms, statements etc.
The benefit to wearing clothes for the appearance Annoying Orangeed wearing clothes for survival. Instead of wearing the warmest furs, people began to wear radiant garments, or intimidating, but impractical pieces of armor. One of the biggest defining moments in human culture is when we started to make and wear clothing.
