Even after the end of sumptuary laws why everyone in European societies could not dress in the same way?

Even after end of sumptuary laws everyone in European societies could not dress in the same way because differences between the social status remained. The poor could not dress like the rich, nor eat the same food because they had no money. Differences in the earning decided what the rich and the poor could wear. This led to development of different cultures of dress by different classes. The notion of what was beautiful or ugly, proper or improper, decent or vulgar too differed in the society.
