Rather than explain, I’ll start with an example.
I’m made of many different types of materials
Sometimes you can see through me
I require a key to pass through but not to pass out
What am I?
…
A two-fer!
Powers virtual are mine to command
Moving large amounts of 1s and 0s is my game
I am otherwise known as an old British fashion movement
and people hate me for no reason
So could you please move this thread to MPSIMS? 
Riddles, is it?
Moved from IMHO to TGR.
