Don't dress nicer than the boss is all I'm saying.
meh. My job I started recently I was dressed nicer than everyone on my interviewing panel and the boss who was in the office but not on my interview panel. I wasn't told anything about dress code between the 2 or 3 phone interviews nor did I ask. I was raised on suit and tie for interviews and that's what I did as I always have.
Even after getting job offers for this or previous jobs, I often dress nicer than the boss in the office. I've never once heard that to be bad and even been complimented by higher ups for doing so. Now if they were cursing my name and talking shit back in their office behind my desk, I don't know. :|
Office dress is pretty casual here at my new job, more casual than any professional job I've had before, but I still dress a few notches higher on many days. Part of it is just my personal style in business settings. Call it a consequence of working in the men's department of Nordstrom before maybe. I have lots of suits, slacks, and shirts in my closet. I don't like to see them just sit there and collect dust. My suits are hung right next to my jeans and comic book/nerd shirts. I personally don't feel uncomfortable in suits or ties nor do I think it's weird to dress above what's the norm in your place of work.
I agree with whoever said wear the nicest thing you have but if you don't have a suit on hand maybe not be concerned with going digging for your one suit that might be in the garage or go out and buy one.
