For his exploration on Crab Key, Bond wears a light blue cotton pique knit shirt tucked into light blue trousers. The polo shirt has a subtle horizontal stripe, ribbed collar and cuffs and a two-button placket. The trousers sit at the waist and have button-waist-adjusters, an extended waistband that closes with two clasps, and two rear pockets.
There are actually two different pairs of trousers worn in these scenes, and they differ in the pockets. One pair has frogmouth pockets and the other has slanted side pockets. The trousers have a visible hem, but Bond often wears them rolled up.
Bond’s shoes are dark blue canvas two-eyelet derbies in most of the shots, though in one shot they are slip-ons.
