It's not cool right now. It may be cool again in a while. If you do it now you may be a trendsetter.
The problem is that if you do it and you aren't in a rock band, it's always going to look like you're trying to look like you're in a rock band... unless the total value of all the clothes you're wearing is over $2000, and then the people who know that they're worth that much will look at you and say 'Hey, it's maybe a new look.'
How's that for an analysis? : )
