Uniform

The school is known for its traditions, including a uniform of black tailcoat (or morning coat) and waistcoat, false-collar and pinstriped trousers. Most pupils wear a white tie that is effectively a strip of cloth folded over into a starched, detachable collar, but some senior boys are entitled to wear a white bow tie and winged collar ("Stick-Ups"). There are some variations in the school dress worn by boys in authority, see School Prefects and King's scholars sections. 

The long-standing claim that the present uniform was first worn as mourning for the death of George III is unfounded. "Eton dress" has undergone significant changes since its standardisation in the 19th century. Originally (along with a top-hat and walking-cane), Etonian dress was reserved for formal occasions, but boys wear it today for classes, which are referred to as "divisions", or "divs". As stated above, King's Scholars wear a black gown over the top of their tailcoats, and occasionally a surplice in Chapel. Members of the teaching staff (known as Beaks) are required to wear a form of school dress when teaching.

From 1820 until 1967, boys under the height of 5'4" were required to wear the 'Eton suit', which replaced the tailcoat with the cropped 'Eton jacket' (known colloquially as a "bum-freezer") and included an 'Eton collar', a large, stiff-starched, white collar. The Eton suit was copied by other schools and has remained in use in some, particularly choir schools.
