Does It Matter How You Look?

I'm asking this question over here, does it matter how you look and dress for business?

After people had so much trouble with how The Apprentice guy, Danny, looked and dressed and then he was fired, I just had to ask about that. What do you think? Does it matter how you dress and what you look like?

Can I mention, Danny was apparently an MIT Media Lab guy, according to his bio, and I can tell you, having met a few folks from there, he looks pretty good comparatively.
