Don't Look Now

Some time after the drowning of their young daughter, Christine (Sharon Williams), in a tragic accident at their English country home, John Baxter (Donald Sutherland) and his grief-stricken wife, Laura (Julie Christie), take a trip to Venice after John accepts a commission from a bishop (Massimo Serato) to restore an ancient church. Laura encounters two elderly sisters, Heather (Hilary Mason) and Wendy (Clelia Matania), at a restaurant where she and John are dining; Heather claims to be psychic andâdespite being blindâinforms Laura she is able to "see" the Baxters' deceased daughter. Shaken, Laura returns to her table, where she faints.
Laura is taken to the hospital, where she later tells John what Heather told her. John is sceptical but pleasantly surprised by the positive change in Laura's demeanour. Later in the evening after returning from the hospital, John and Laura engage in passionate sexual intercourse. Afterwards, they go out to dinner where they get lost and briefly become separated. John catches a glimpse of what appears to be a small child (Adelina Poerio) wearing a red coat similar to the one Christine was wearing when she died.
The next day, Laura meets with Heather and Wendy, who hold a sÃ©ance to try to contact Christine. When she returns to the hotel Laura informs John that Christine has said he is in danger and must leave Venice. John loses his temper with Laura, but that night they receive a telephone call informing them that their son (Nicholas Salter) has been injured in an accident at his boarding school. Laura departs for England, while John stays on to complete the restoration. Under the assumption that Laura is in England, John is shocked when later that day he spots her on a vaporetto that is part of a funeral cortege, accompanied by the two sisters. Concerned about his wife's mental state and with reports of a serial killer at large in Venice, he reports Laura's disappearance to the police. The inspector (Renato Scarpa) investigating the killings is suspicious of John and has him followed.
After conducting a futile search for Laura and the sistersâin which he again sees the childlike figure in the red coatâJohn contacts his son's school to enquire about his condition, only to discover Laura is already there. After speaking to her to confirm she really is in England, a bewildered John returns to the police station to inform the police he has found his wife. In the meantime the police have brought Heather in for questioning, so an apologetic John offers to escort her back to the hotel.
Shortly after returning, Heather slips into a trance so John makes his excuses and quickly leaves. Upon coming out of it she beseeches her sister to go after John, sensing that something terrible is about to happen, but Wendy is unable to catch up with him. Meanwhile, John catches another glimpse of the mysterious figure in red and this time pursues it. He corners the elusive figure in a deserted palazzo and approaches it, believing it to be a child. Instead, it is revealed to be a hideous female dwarf, and while John is frozen in terror the dwarf pulls out a meat cleaver and cuts his throat. As the life drains from him, John realises too late that the strange sightings he has been experiencing were premonitions of his own murder and funeral.

Question: What article of clothing did John see that reminded him of a similar item worn by Christine when she died?
