After a couple of days in New York City, Rosé has her summer uniform down to a science—and it all revolves around a black bra.

Last night, the Blackpink singer galavanted through the streets of Chelsea dressed in a gathered black cotton square-neck bra top with a delicate ruffle detail on the strap. She paired the bralette with a matching high-waisted pair of button-up boxers. She infused the sweet summery look with a masculine edge, thanks to a pair of baggy, low-slung jeans in a rugged stone wash, styled with a pair of chunky sneakers.

The previous day, Rosé opted for two looks that followed the same formula. Spotted strolling through SoHo during the day, she layered a dainty white lace top with an asymmetrical hem over a black triangle bra, which she paired with slouchy mid-rise blue jeans, a pair of surfer-dude-friendly flip-flops, thick cat-eye sunglasses, and a white quilted Chanel crossbody. She updated the look for night, swapping her white top for a black lacy camisole (which showed off the same black bralette), cinched with a slim oxblood belt.

If you’re wondering how to incorporate your underwear into your summer style, look no further than Rosé, who just demonstrated three very viable options.
