'stylishly-decorated' originates from the combination of 'stylish' and 'decorate', where 'stylish' comes from 'style' meaning 'a particular form or design', and 'decorate' from Latin 'decorare' meaning 'to adorn'.

'stylish' evolved from the Old French 'estile', and 'decorate' from the Latin 'decorare', eventually forming the modern English term 'stylishly-decorated'.

Initially, 'decorate' meant 'to adorn', and 'stylish' referred to 'a particular form', evolving into the current meaning of 'fashionably adorned'.
