It’s Avon Miss Lollypop cologne mist, which here appears sans white hat. This fragrance for girls was launched in 1967: according to the reviews I’ve read, it was a gourmand perfume, smelling like candy.
While Combo (Stephen Graham) is getting ready to have a bath, we get a glimpse of Avon Charisma perfumed talc in Lol and Woody’s bathroom shelf.
One of the most hilarious scenes of this film is set in a London leather bar, taken by storm by a group of women from Dulais, Wales. Gail (Nia Gwynne) and Gwen (Menna Trussler) ask a rubber man (Nick Blair) how he gets into his latex catsuit. He obviously uses talcum powder, something that Gwen uses too, for a different purpose. She explains she uses lily-of-the-valley powder, such a classic British scent!
Gwen is a working-class lady, so I guess her talcum powder is a traditional product, not too fancy nor expensive. Taylor of London, Bronnley, Marks & Spencer, Morny and Yardley would be excellent choices.
