It’s work safety attire. When men wear it it’s “why are you wearing those work clothes” women can wear them because no one will assume they’re work clothes because women don’t (normally/traditionally) do those jobs.
In the same way that men don’t wear suits in a casual setting they don’t wear other work attire in a casual setting.
A lot of this is in the “it might be fine” territory, but weaponisable laws concern me. It’s not like public trust in the police is particularly high right now either for good reason.
