Bare-Down-There Drawbacks
Ditching your undies has a few small pitfalls. One minor risk is a rash that can result from the delicate skin down below chafing against your pants.

If you're wearing a skirt and then sit on a lice-infested towel, they have a direct path to your privates.
is it safe or not?
