Realistically, Lara Croft could go through all her adventures like this. It’s not like booty shorts provide that much protection anyway.
Girls don’t have balls, so it’s not like she has to protect anything vulnerable. She has no penis either, so no need for support; she can walk naked comfortably with nothing flopping in the way.
If she’s exploring long abandoned tombs alone, why not? And if she encounters any enemies, it’ll be a very useful distraction 😀
