I take exactly the opposite tack - whatever I'm wearing I say "I bought it for $20 from a guy on Canal Street"
Then they say "I dunno - looks pretty nice for a fake, I think you're bullshitting me"
Then I just agree with them, and say I was just joking.
I was joking, too - I got it for $300 from Angus in China.
But by now they've convinced themselves it's a Gen, and I don't argue about that.
