“He went into his room and dressed in his old dark blue tropical worsted suit, a sleeveless white cotton shirt and a black knitted tie, looked in the glass to see that the Walther didn’t show under his armpit and went down and out to where the car was waiting.” (Chapter 4)
One should always wear long-sleeve shirts with a suit. In this case, “sleeveless” means short-sleeve. Short-sleeve shirts are always casual shirts, though Ian Fleming himself wore them with his suits to both stay cool in Jamaica and to avoid dirty cuffs. On most people, wearing a short-sleeve shirt with a tie gives off the low-level office-worker look, like Dilbert. Though I’m sure Bond is able to pull it off a little better.
“Bond fitted himself out with cheap black canvas jeans and a dark blue shirt and rope-soled shoes.” (Chapter 7)
“He laughed with real pleasure that her fear had been drowned in the basic predicament of clothes and how to behave, and he laughed at the picture they made-she in her rags and he in his dirty blue shirt and black jeans and muddy canvas shoes.” (Chapter 13)
“Through the door was a grey painted stone cell about fifteen feet square. There was nothing in it except a wooden chair on which lay, laundered and neatly folded, Bond’s black canvas jeans and his blue shirt.” (Chapter 17)
To all those who don’t approve of Daniel Craig wearing jeans, Fleming himself approved jeans, but in black canvas. He never mentioned denim on Bond. These canvas jeans are perfect for a rough mission in the Caribbean.
