How to be more comfortable when I’m around kids who are wearing shorts?

Whenever I see kids wearing things like shorts and tank tops, it activates a lot of anxiety. It can be really scary and awkward to see kids showing parts of their bodies my mind identifies as private, vulnerable, and unsafe to show (not unsafe because of me, obviously)

Of course, it's not the kids' fault and they can wear whatever they want. I've been trying to be more comfortable around this, but it's so difficult.
