The more people around me dress down, the more I want to dress up. I'm contracting for NSW Health (IT, not clinical stuff) at the moment and business casual with a twist best describes how most people here dress. The guy next to me seems to favour crumpled polyester suits and white trainers.
What I want to say, is dress for yourself first and foremost, and not for others. Personal style is not the same as conformity. I definitely raise a few eyebrows when rocking a three piece here, but when worn with confidence it just works. I must admit to wearing silk knit and wool ties far more than when I was working in the CBD. And more sports coat/odd trouser combo's. But always a tie and PS. And decent shoes.
In my experience people very quickly get used to what you wear, irrespective of what they are wearing. Warning: Spoiler! (Click to show)
Fuck what they think, grow a pair and dress like a man. The chicks will dig you for it and you will look back without regret.
