Lara wears this in Tomb Raider III, in the Nevada/Area 51 levels.
This outfit has a similar style of top to the classic outfit, with a scooped neckline, but it's cropped to reveal Lara's belly, and it's black or dark grey.
Her camouflage pants are blue, low on her hips and tucked into black boots, with a black leather belt fastened with a silver rectangular buckle.
In terms of fabric, the top should be stretch, and it doesn't seem as shiny as the classic outfit.
The trousers are probably a hard wearing cotton.
