Sean Connery wears a casual outfit for a brief boat outing in Woman of Straw. On top he wears a black and brown horizontal-striped crew-neck jumper, probably made of cashmere. The jumper has black ribbed collar, cuffs and hem. The tan gabardine trousers have single reverse pleats. Connery was rarely seen wearing trousers with reverse pleats in the 1960s—he mostly wore forward pleats. Whilst they aren’t particularly slimming, they fit his large thighs very well.
While I would prefer the trousers with forward pleats or plain front, it otherwise looks like a very sensible casual outfit.
