Every now and then I’m asked about the legitimacy of the silk facing on the white dinner jacket featured in Indiana Jones and The Temple of Doom. My answer is that while it might be legitimate for the 1980s production timeline it certainly wasn’t for the 1930s narrative. Of the dozens of Depression-era white DJ references I have on file from leading menswear periodicals, none of them suggest anything but self facings. Of course it’s always possible that some tailor somewhere constructed such a model but it would be the exception that proves the rule.
On a related note, the black waistcoat would have been equally unorthodox back in the day. It would appear that the film’s costume designer is on par with when it comes to being clueless about period formal attire.
