Lara wears this in Tomb Raider III.
This is quite similar to the classic outfit, but the top is much shorter.
I would say a stretch fabric would be good, but latex if you fancy it, in a white or light blue.
The shorts have rolled hems and are an olive green, probably cotton.
In some pictures it looks like a green and black camouflage pattern.
Details on the belt, shoes and backpack can be found on the classic costume page
