I have been working as a contractor with a local small engineering firm. Only about 10 total employees and I interface with the owner for my projects. Most employees including the owner wear jeans and polos.
Given that I have at least met most people in the workplace so far--should I negate the usual tip to "dress for the job you want"? I.e. should I skip the full suit and tie or at least leave the jacket at home?
Or should I go somewhat more casual: slacks, gingham shirt, skinny tie.
I should also note I only own a black suit.
