The developers have had a little fun with Lara in this costume I think!
The outfit itself is very similar to the biker costume.
Her trousers are black leather and tuck into big black and grey boots.
Her leather jacket is mainly black, with purple details and finishes at her waist.
Her top looks like black lace over white or grey lining and is partly undone at the neck.
What really sets this outfit apart is Lara's makeup. Normally minimal, she now has a whole new look.
She has a black mascara "tear" running down each cheek and her lips are also a dark shade of burgandy.
If you look closely you can also see she has black polish on her fingernails.
Also, she has blue eyes with the Goth outfits, but no other.
Then she also sports her Legend utility belt and backpack.
