At showtime for Paris-Asia you can have the crew wearing:
blouse (blazer if you're insecure)
top-coat for blazer with white shirt underneath
leather jacket
cop-coat (North Face Parka)
all are technically in uniform.
I own all of the above except the Parka.
Don't care what we choose, but we should pick one.
It shouldn't come from management, but from us.
Pins, lanyards, and bag tags are great, but everyone looking the same is also an easy way of showing solidarity.
