The top model stepped out today to celebrate the opening of the Stuart Weitzman London Flagship Store in the U.K., and she made a comfortably chic statement in a sleepwear-inspired Fleur Du Mal onesie. The stylish black number was crafted from silky black material and came complete with contrasting piping on the seams and pockets. The 21-year-old topped off her fashionable PJs with a tailored Smythe coat that featured structured shoulders and a two-button front closure. Hadid accessorized with a wow-worthy choker necklace and a pair of black-and-white Stuart Weitzman sandals. The blonde bombshell pulled her long strands back into a super sleek bun and added a bold red lip color to her perfect pout.
