Selena Gomez tapped into the viral "office siren" fashion trend during a World Mental Health Day event for her brand, Rare Beauty.

Gomez celebrated the second year of her makeup company Rare Beauty and Sephora’s Make A Rare Impact Campaign in honor of World Mental Health Day by doing a meet and greet with fans in Soho. For the event, she opted for a full on Khaite NY look, including the brand’s low-cut Toto bodysuit in black and their Marinta pant in the color chalk.

In recognition of World Mental Health Day on Oct. 10, Sephora will donate 100% of global Rare Beauty sales to the Rare Impact Fund.

For the special occasion, Gomez made a case for statement belts with an ensemble by Khaite. The “Only Murders in the Building” actress wore a sleeveless black bodysuit with a scoop neckline, paired with white wide-leg trousers and a studded belt.
