Though I don’t know if it was a trend in 1965, Bond wears a matching sports shirt and trouser set made of cotton poplin or a linen and cotton blend in Thunderball. And it’s in a vivid royal blue. Out of Sean Connery’s casual Bahamas outfits in Thunderball, this one dates the worst. It looks like a well-fitting set of pyjamas, but Connery pulls it off. The shirt has a camp collar, four large white buttons down the front, and a straight hem. The hem of the short sleeves is turned up and sewn all the way around. The back of the shirt has shoulder pleats, which are pressed all the way down the shirt. There are two large lower patch pockets on the front.
Though we see little of the trousers, they have a tapered leg and are pressed with a crease. Bond wears shiny black slip-on shoes and no socks. The shoes are possibly made of rubber. Goldfinger and Thunderball are the only times that Bond wears a straw hat. This pork pie hat is natural straw with a blue and white checked cotton ribbon. The hat has a telescopic crown with no pinch, and a short brim that’s turned up in back. A short brim is unusual for a straw hat since it provides little shade from the sun, but it’s part of the more typical pork pie style. To make up for the short brim, Bond wears the Wayferer-style sunglasses that we see more of later in the film.
