'lookers' originates from English, specifically the word 'looker', where 'look' meant 'to direct one's gaze' and the agentive suffix '-er' meant 'one who performs the action'.

'looker' changed from Middle English forms such as 'loken'/'looken' (verb 'to look' + agent suffix) and eventually became the modern English noun 'looker' (with plural 'lookers').

Initially, it meant 'one who looks' (a watcher or observer), but over time it also developed the informal sense 'an attractive person'.
