What if you're at an overly-corporate place being the jeans & t-shirt person?

Throughout modern history tech founders used this to great effect against suits.

My theory is that radically different dress from the norm (whether dressing up or down) can be advantageous provided you remain utterly confident and bring value to the table.

Being utterly confident means people will assume you bring a lot of value to the table, whether or not you do. The signals you give are usually the first and some of the strongest ones that people look at. Of course, if you're a total charlatan, you'll be exposed eventually; but you'll get much farther with excellent confidence in mediocre work than you will with wavering confidence in excellent work.

That said, I almost always stand out in my manner of dress, and it's bought me no particular advantages. It would surprise me if "the tall girl with the great outfits" was not a good enough description to get most people in my area to identify me. Still, being visually recognizable confers no immediate advantage, beyond that whenever I meet people they remember me and have seen me around before. (I just love fashion, so I do it for me more than anything else)

Taleb talks about this in Anti-fragile. Rock Stars can wear whatever they want and it doesn't hurt them in their career. In contrast a lawyer or accountant could seriously hurt their career showing up to work with an unusual outfit on.

In the Software world you can have it both ways. Showing up in sweatpants and a vulgar t-shirt may cause people to think you are so good that you don't have to care. But also to think that you will never be in management
