Even Brazil’s president, Luiz Inácio Lula da Silva, has received one, after Wagner Moura wore it in The Secret Agent

It is glimpsed in just a few scenes in The Secret Agent, the Brazilian film nominated for four Oscars and two Baftas, but that has been enough exposure for a vintage yellow T-shirt to become the latest object of desire among Brazilian progressives.

The garment, worn on screen by Wagner Moura, was first produced in 1978 by Pitombeira dos Quatro Cantos, a carnival group in the coastal city of Olinda, which until recently would sell just a few dozen a month.
