'old-fashionedly-done' originates from the combination of 'old-fashioned' and 'done', where 'old-fashioned' refers to something that belongs to or is characteristic of a past era.

'old-fashioned' changed from the Middle English word 'olde' and 'fashoun', eventually becoming the modern English word 'old-fashioned'.

Initially, it meant 'in a manner typical of a past era', and this meaning has largely remained the same in modern usage.
