Boobs are having a moment in fashion right now — from Emily Ratajkowski’s sideboob-freeing dress to Zoë Kravitz’s ongoing sheer party on the red carpet. And now Khloé Kardashian has officially hopped on the anti-bra bandwagon.

On Thursday, the reality star attended younger sister Kylie Jenner’s launch party for her new canned cocktail brand, Sprinter, at Catch Steak in West Hollywood, where bras were apparently an optional article of clothing when it came to the dress code. As the only sibling in attendance, Kardashian had to represent and bring the family’s signature brand of Sєxy to the event.

For the occasion, the Good American founder wore a see-through LBD that featured an off-the-shoulder neckline that doesn’t go well with a bra. Ditching the undergarment altogether, Kardashian wore nothing underneath her black bodycon minidress except for a pair of black briefs and sheer black stockings. She rounded out her look with black pointed-toe pumps, nighttime sunglᴀsses, and a mini blue Birkin bag for a pop of color.When it came time for glam, Kardashian styled her long blonde hair in loose curls with a center part and opted for a bronzy makeup palette that consisted of ɴuᴅᴇ lips and copper-colored eyeshadow.
