Of course, most people wearing pajamas in the airport after a long flight would look more than a little wrecked — hair all a mess, face covered in creases from being awkwardly mashed up against the window, a hint of dried drool at the corner of their mouth — but not Ariana! She paired her too-cute unicorn onesie with an equally cute black cat-eye and two little half-loop hair buns in place of her signature cat-ear headband. She also, somehow, managed to make the giant, shapeless onesie actually look kind of good — Dare I say "sexy," even? — by letting it fall off one shoulder to reveal the black tank top and matching bra underneath.
