James Bond quickly puts on some clothes to “take a little exercise” late at night at Shrublands health clinic in Thunderball. He wears the same Anthony Sinclair light brown flat front cavalry twill trousers with frogmouth pockets he wears earlier, and throws on a black lightweight cashmere long-sleeve polo shirt. The polo shirt has a three-button placket with white buttons. Bond rolls up the sleeves up over the elbow and they stay firmly in place. However, there is a continuity error in this scene: in the close-up when Bond unwraps Major Derval’s face his sleeves are no longer rolled up. Bond takes his exercise without shoes or socks.
He later wears this polo again in the Bahamas as part of an all-black outfit.
