'suitably-dressed' originates from the word 'suit,' which comes from the Latin word 'sequor,' meaning 'to follow.' The term 'dressed' comes from the Old French 'dresser,' meaning 'to arrange.'

'suit' evolved from the Latin 'sequor' to the Old French 'suite,' and eventually became the modern English word 'suit.' 'Dressed' transformed from the Old French 'dresser' to the Middle English 'dressen,' and eventually became 'dressed.'

Initially, 'suit' meant 'to follow or pursue,' but over time it evolved to mean 'appropriate clothing.' 'Dressed' originally meant 'to arrange or prepare,' and now it means 'to put on clothes.'
