It seems quite remarkable today, given the inseparable link between Eton and tails, that there was a time comparatively recently, that things were far more relaxed and Etonians were encouraged to dress in a style and manner of their own taste.
In 1862, the Headmaster Dr. Balston was questioned by the Public Schools Commission about school dress and the apparent lack of any particular uniformity.
He agreed that there wasn’t, with the exception that every boy was obliged to wear a white neckcloth and ‘Round Hat’ (top hat). Junior boys wore a turn down collar - known as the ‘Eton collar’ - a black tie and a short jacket, affectionately known as a ‘bum-freezer’. This was worn by boys under 5’4” and wasn’t finally phased out until 1967.
He also mentioned that they wouldn’t be allowed to wear anything out of the ordinary, such as a yellow coat or something of similar hue, but they were allowed to follow their own taste in respect to choice of material and style.
Having been at Eton himself in the early 1830s, he was used to an even more informal dress code, where, depending on the fashion, the dress changed ‘A La Mode’, at one time even sporting blue coats with yellow waistcoats.
