Bank dress code: "makeup will enhance your personality"

Overall I think it's an intriguing idea. I've known quite a few people (myself included) that have harmed peoples' perceptions of them simply by not appearing professional. I had used to think it would be a big burden on my time, but it's amazing what taking 5 - 10 minutes a day will do to improve your image.
People say it shouldn't be so, but it is. Recognising that and using it is a form of societal hacking.
Ideabolt: How about a startup that gives fashion tips for hackers? How to give off that "I'm intelligent and don't give a damn" feeling with gusto, what t-shirts to buy? What shoes does Sergei wear? Where does Steve gets his black turtlenecks, etc.
The only thing that sort of comes close in fashion are sites such as Threadless, betabrand, etc., mostly geeky t-shirts. But no site for how to do the whole look.
What you are proposing, I think, is to take the idea even further, give advice on relationships, dealings with pointy haired bosses and so on. I think that would be great.
If hiring is any indication, I know that in France (not 100% sure specifically about Switzerland) it's pretty much required to submit a photo of yourself with any job application/CV. I think this is a good reflection of the kind of thought process that goes on in some workplaces.
If they think they can judge your worthiness for a given position by your appearance in a photo, I can only imagine the importance they put on daily dress at the office.
P.S. When did "Don't" enter the French language (p 42)?
