Cara Delevingne turns head with an unusual line down her chest at the 2016 London Fashion Week.

CARA Delevingne doesn’t play by the rules. And when she stepped out during London Fashion Week overnight, she was flaunting a rather unusual accessory.

Attending the Burberry show, the model and actress rocked a black velvet babydoll-style dress with a ruffled cape and plunging neckline.

But instead of accessorising with a statement necklace or choker, the 24-year-old decided to draw a bold black line from the top of her neck down to her bellybutton.

Cara Delevingne arrives at the Burberry Spring/Summer 2017 fashion show at London Fashion Week.

While some have speculated the line is a thin piece of fabric, others think Cara may have gotten creative with her eyeliner pencil while getting ready for the night out.

Will we be drawing on our chests with eyeliner in six months? We’ll wait and see.
