The pictures on this page are all pre-release, so the costume may have changed slightly now the game is out.
Also, some of the promos are mirror images of each other so it's hard to tell which side some things are on.
Lara's t-shirt is a tight fitting stretchy v-neck, with a very plunging neckline.
It has a chocolate brown front panel and charcoal black sides, with a brown back.
In some of the pictures the black panels appear to be a breathable mesh fabric.
The top is cropped, finishing above Lara's belly button.
There are two bottom-half versions of this outfit, the trousers version is pictured above.
Her trousers appear to be black leather pants, low slung on her hips and tucked into her boots.
The second variation is charcoal shorts with black panels at the sides.
The shorts are also hipster style and are very short and snug.
Lara's holsters are black, probably leather and canvas webbing which fasten with a chunky black buckle.
There is a pouch on one side which seems to house her grapple.
Her boots are heavy biker boots in black leather with silver metal accents.
The boots have two straps around the leg and one across the foot.
When worn with shorts, there are thick white socks visible under the boots.
There is no good shot of her backpack, but it is a compact black style.
The shoulder straps are linked across her chest with a thin strap of leather that goes behind her back.
The shoulder straps also have silver D-rings on them.
Lara wears black (probably leather) fingerless gloves and has a black band on one wrist.
