Thanks for everybody's input on this. I understand the point Sil was trying to get across, and I think we're sort of digressed from that, but I like/appreciate what everyone's said. There's some good knowledge and experience shared here

I am still shocked when my recruiters remind me to wear a suit and tie when going for interviews. I look at them like "duh" but they have told me that they had recruits going in wearing jeans and such. Shocking how people don't know how to dress for success. I heard wise words once "Dress for the job you want, not for the job you have."
I've heard this before and have wondered a few things. So I understand that there's this societal hierarchy of clothes. Jeans and t-shirts, slacks and button-ups, 3 piece suits (not comprehensive, but an example). So the quote "dress for the job you want, not for the job you have." This implies that you'll need to wear clothes higher up on the clothes hierarchy to get a "better" job. Does this train of thought only apply to a job interview? Or does the type of clothes you wear to an interview reflect the clothes you'll be wearing on a daily basis (from an infosec position perspective)? For me, the job I want isn't wearing suits everyday. Is this really what higher security positions require? Or as I asked above, is it only for the interview process?
<rant>Maybe I'm just ignorant to the whole hiring process and what you wear to an interview implies, but I think that in this day in age where it's way more common that you can't judge a book by it's cover, we'd be evolving out of this "you need to wear a suit to get a better job" idea and actually interview for a persons knowledge.</rant>
