Dear Shaded Viewers and Diane,
Much has been said already about Ursula Andress's costumes in The 10th Victim (La decima vittima, 1965), designed by Guido Coltellacci and made by the Sorelle Fontana to look dangerous and daring in so many ways. Instead, I would like to share with you this extract from Anna Battista's contribution to the beautiful catalogue If Looks Could Kill: Cinema's Images of Fashion, Crime and Violence; where she skilfully describes Mr. Mastroianni flawless outfit.
"His suit is impeccable and has a futuristic twist: the trousers are fitted and have two front slit pockets: the collarless Nehru jacket (that suits his needs perfectly, thanks to a high armhole carefully designed not only to allow him to move freely, but also to shoot comfortably) is slender and not darted inward to the waist, so that the entire look is one of comfort, although slightly square in shape. The shoulders of this silhouette are gently sloping and Velcro is used instead of buttons. The tailor-made creations sported by Marcello are tempered by a sartorial softness, making him look like a bored futuristic dandy." (Battista, 2008)
No wonder then that Tom Ford affirmed, back in 1998, that both actors might without doubt have been dressed by Gucci.
