Basically, you are just a locomotive tree wrapped by skin and loaded with emotions which gives out carbon dioxide through respiration. Homosapiens.
I have no idea on why to dress, but lemme say few things on how to dress.
Skin is the largest organ in human body. It is the best guard which ensures your safety from temperatures, microbes, damaging sunlight etc. And so, you must ensure whether the dress you wear never disturbs skin from doing its duty. Let it stay free. According to the climate, surrounding area and the type of your skin, choose your skin friendly dress.
The average square inch (6.5 cm²) of skin holds 650 sweat glands, 20 blood vessels, 60,000 melanocytes, and more than 1,000 nerve endings.
Before dressing up for any occasion, make sure that you are not disturbing each square inch of your skin. It isn’t a fence so that you could colour or hammer or stick ‘no parking’ posters on it. Wear a smile and not brands. Let your skin be your favorite beautiful cloth.
