Is it necessary to wear safety pants to wear jk of this length?

I suggest you wear safety pants. This length of jk is a little easy to strip off, especially when you squat down to tie your shoelaces or pick things up the steps. At present, there are quite a lot of hooligans and salty pig hands in society (my sister has met them). If you haven't studied boxing or Sanda, it may be safer to wear safety pants (only my personal opinion). Girls must protect their privacy when they go out. When you meet a salty pig hand, you must not blindly endure it. If they want to resist him, they can call the police uncle if necessary.
