Hailey Bieber Stepped Out in a Sporty-Chic Jets T-Shirt and No Pants

Who knew a T-shirt could be sexy? Hailey Bieber took comfy-dressing to the next level with an oversized tee and nothing else.

The model stepped out for lunch with friend Justine Skye in Los Angeles on Thursday in a sporty-chic look that included a long-sleeve graphic Jets Football T-shirt, which she wore as a dress. She paired the look with the Saint Laurent Le 5 à Hobo Bag in Smooth Leather, white socks, New Balance X Casablanca 327 sneakers, and the black Saint Laurent 462 Sulpice Sunglasses.

Hailey also accessorized with hoop earrings and several layered gold necklaces, one of which paid a sweet tribute to her husband Justin Bieber. Attached to a gold chain were diamond charms of Justin's initials: JDB (Justin Drew Bieber). She completed her outfit with a black face mask and pulled her hair into an ultra-tight bun.

"In bed with our new Tiffany brand ambassador @haileybieber, who wears Tiffany HardWear and Tiffany T with diamonds," the brand wrote alongside a cute photo of a smiling Hailey with her hands on her face.
