Her tattered clothes

She looks curious as to how they ended up without her. She then notices how wet and torn up they are. She swims up to the surface for a brief moment. She gasps for air and ponders, if they are still ok enough to wear. Lara dives back down to the debris, with the unfamiliar but exciting feeling of being naked.

As she swims to the debris she starts thinking about if there are inhabitants of the island. She ignores that thought in disbelief and continues onwards. She grabs the torn cloth and swims to land. The nude adventurer tries to put on the clothes. They tear up like wet paper from being there for so long and fall like leaves from a tree.

She looks for any means of covering up but remembers there are no people. Still she tries to find some extra clothes. She scans the trees and gets an idea! She climbs up and starts plying leaves from the branches. She ties them together with excess string to make a makeshift bikini. Whatever works works.
