Try to craft some clothes

The leaves seem big enough, why not go for a jungle girl look? I mean, it will still be an embarrassingly skimpy look, but better to be decent than not, right? You grab a big, long leaf from the ground and wrap it around your crotch. Yes, it could work.

You need a way to hold it in place. Maybe you can tie several leaves together to craft some sort of rope? Nah, that won´t do. They are too fragile. Luckily for you, you can spot a vine near your feet. You pick it up and fumble with it for some minutes. …It works! By tying the vine like a belt, you are now wearing half of a loincloth.

You reach into a bush to pull another leaf for your makeshift garment. You grab the foliage and pause. Your blood freezes over as your fight or flight instinct kicks in. “S-s-s-spider! AAAAH!”

You jump back and shake your hand. The spider is gone, but it could be somewhere on the floor still! Your bare feet take a couple of steps back. Where is it? You feel something brush against your waist and look down with alarm. Ants! They are swarming your stomach and tighs! Where did they come from? Oh no, they are coming from the vine!

Birds fly away and trees shake with the power of your scared scream. With **** you didn´t know you had, you tear up your loincloth and beeline it for the lake, jumping in the water to get rid of as many bugs as you can.

You take a few minutes to calm yourself on the cold water before cautiously going back to the shore. Why did it have to be bugs? Oh hell no, you aren´t going to try that again.
