Stella teamed her look with black-and-white slides, which she wore with white socks.
The Belgium-beauty kept her blonde unstyled hair off to the side, while hiding her fresh face behind a pair of gold-rimmed sunglasses.
Stella accessorized her look with a dainty silver choker and black leather backpack that she carried over her shoulder.
She also was seen holding tightly onto her iPhone and earphones as she walked out of the terminal.
