Comfortable clothes and dressing up are not mutually exclusive. Just because a nerd might not know how to find comfortable dressier clothes does not make a suit uncomfortable in itself.

And what I was trying to say is that a rock star (insert profession here) is more likely to be able to get away with saying "I'm going to wear whatever the f--- I want to wear" than someone who is just good, especially in a workplace where wearing jeans and t-shirts is not an accepted norm. And that's usually the case outside of the tech startup and creative worlds.
