The model has had a whirlwind 24 hours while promoting the launch of her new skincare line, Rhode.
The model started her day off in an all-black look that combined the best of Matrix-esque fashion and dark academia.
For her next appearance, Bieber opted for a completely different ensemble, wearing an ivory long-sleeved dress from Jil Sander's fall 2022 collection.
While spotted in Brooklyn later in the day, Bieber went for another monochrome moment, this time donning a head-to-toe camel outfit composed of a Sportmax suit and glossy Jimmy Choo pumps.
She accessorized with more gold Tiffany & Co. jewelry and re-wore her Balenciaga sunglasses.
For her penultimate appearance, Bieber again wore Sportmax, this time a structured little black dress from the brand's fall 2022 collection.
The mod look was accentuated with minimal accessories, including her Balenciaga glasses, black Jimmy Choo slingbacks, and drop earrings.
Finally, ending the day with a live interview on The Tonight Show, Bieber looked radiant in a nearly sheer, sequined dress with a keyhole cutout from 16Arlington.
She accessorized minimally, wearing clear heels and gold earrings.
As she ran around New York City spreading the news, she simultaneously put on a fashion show by making five head-turning outfit changes.
Her inky black blazer, a unique piece from Aggi that cinched at the waist, was worn on top of a matching miniskirt.
She accessorized with white socks, chunky Bottega Veneta loafers, tiny Balenciaga oval shades, and gold circle earrings from Tiffany & Co.
Hailey Bieber hit the Big Apple Wednesday for the launch of her Rhode skincare line with a fleet of cars comparable to the Secret Service.
