If you're above a certain age and you go to nightclub and parties, you're going to draw surprised glances from people around you - especially younger people. That's not fair when all you want to do is dance and have a good time. People can't help it, though - the last thing anyone expects to see when going out clubbing is someone who's old enough to be their grandfather getting on down with their bad self.
As this chap knows everyone is going to stare at him whatever happens, he's taken things to an extreme. A crop top would be a bold look on a man of any age - on him it's incredibly brave! He's got no time for people who don't like it though; he's got one message for them on the front, and another on the back. Keep moving along, hater. There's nothing to see here except a man enjoying his evening!
