In Thunderball, villain Emilio Largo played by Adolfo Celi wears a double-breasted navy blazer that has eight buttons with three to button. It’s a very rare style that recalls naval uniforms more than the standard double-breasted blazer does, and as a blazer it’s most famously associated with Prince Charles. Largo treats this blazer like a dressing gown and dons it without a shirt underneath when he gets out of the water after a dive. The only other things he wears with it are his black diving trousers and a burgundy silk day cravat. It’s not an ordinary way to wear a blazer, but aboard his own ship Largo can wear whatever he pleases. There is one scene, however, that shows him more dressed in his blazer, with a white button-cuff shirt and stone-coloured trousers, along with the day cravat.
The blazer is most likely English-tailored and has an appropriate structured, military cut with its padded shoulders, roped sleeve heads and clean chest. It has double vents, jetted hip pockets and three-button cuffs. The shanked buttons are made of polished brass, without any ornamentation.
