Three sailors. Number 1 is a confident, cocky lad, he is very explosive with pirouettes, jazz splits, he winks at the female, his hat is low down. Sailor 2 is more reserved and shy, his cap is further back (see his forehead - maybe a bit dopey), legato feel of the music, drawn out notes to reflect his shy personality. Sailor 3 (Robbins character) who is the leader, wears his cap slightly to the side because he can, swivelling his hips.
