/cgl/ - Cosplay & EGL

Anyone knows how to find more of these type of hats that can be used for lolita? I know it's something like ポリスハット although most of the results just give me your usual regular police hats.
Well, in better words I would like to know what brands can make hats that can be used for millitary lolita since there aren't that many.
I would say a chinese keyword would be fine too, I would've asked for that on the taobao thread but I figured the entire question belonged here anyway
