Selena Gomez has worn what feels like every permutation of a little black dress while promoting her film Emilia Pérez, from Saint Laurent gowns at Cannes to satin blazer minis in New York City. For a London photocall on Oct. 10, she was still on a her LBD agenda in a velvet Schiaparelli gown—but this one included an inside joke just for fashion girls.
Gomez's column gown, styled by Erin Walsh, features a cut-out at the bodice that doubles as a style pun. Circular windows to the sternum are typically called a "keyhole" cut-out. The Schiaparelli dress's opening is in the shape of an actual Victorian keyhole. According to the designer's site, it's made from hammered brass. So, it could easily go from Gomez's dress to the threshold of a townhouse just steps away from her in London.
