When the first class clothes appeared ?

A specialized school uniform, including clothing for the first class, first appeared in the UK in 1552, and in the 18th century the wearing of uniform uniforms spread to the English colonies. Over time, the duty of British children to wear bridges, waistcoats and navy blue jackets installed for all was then canceled, then reintroduced, but survived to the present day.

The successful experience of the British was introduced in the Russian Empire, where specialized clothing for children of the first, middle and senior classes appeared in 1834. Following the example of Russia, the form was worn by Soviet children, and then, after the cancellation of its obligatory nature in 1992, the issue of its introduction again rose in 2012.
