Mass production in the industrial age erased personality, and everyone looked dull and boring. Hippies go shopping in the second-hand clothing market and choose clothes from dead designers or strange countries, which greatly reduces the risk of "shirt collision". This is an act that hippies want to show their individuality.
Compared with the ambitious shopping behavior of most young people, hippies choose DIY, and tie-dyeing has become one of the most iconic fashions of hippie youth, because there are no two identical tie-dyeing. They make their own T-shirts by themselves.

Hippies are a cultural movement without unity. They opposed nationalism and Vietnam War with a commune-like wandering life style without declaration and leaders, advocated non-traditional religious culture, criticized the values of the middle class in western countries, criticized the government's restrictions on citizens' rights and interests, the greed of big companies, narrow traditional morality and the inhumanity of war.
Call the institutions and organizations they oppose "the establishment". At that time, hippies wanted to change their minds (by using drugs, mystical practice or a mixture of the two) and get rid of the mainstream of society. Far East metaphysics, religious practice and totem belief of primitive tribes have great influence on hippies, which evolved into a new era movement of mysticism in the 1970 s.
