But seriously the model makes everything look cool, even exercising. Hailey was spotted heading to workout in Los Angeles, and her activewear included the tiniest bra and short set. The model paired her neon green sports bra with booty shorts in an even brighter shade, both from Alo. Getty Images The barely-there, ab-baring attire was accompanied by an oversized ivory button up, a matching sweatshirt tied around her waist, white socks, and Nike sneakers. She accessorized with a short gold necklace and a body chain that was worn beneath the top and fastened behind her midsection. As Hailey made her way into Forma Pilates for her scheduled session, she wore her expensive brunette tresses in a messy half-up, half-down style secured by a white scrunchie, and she finished off the look with a pair of square-framed black shades.
