There is a saying:
Dress for the job you want, not the one you have.
I have always understood this as implying that this is a way to help attain "the job you want".
This article references a fairly recent poll from executives, but I'm not sure how great it is.
Several comments and answers on workplace.stackexchange.comgiving opinions or anecdotes claiming it works:
"How to dress if there is no dress code?" 2nd highest answer. (The asker's real concern is a little off the topic of what I care about, but the sayings are still referenced.)
I've had a little difficulty in finding any real research or evidence supporting or denying this approach works.
I would think this claim, that dressing as a certain rank/position would help one attain that position, could be tested.
Is this real wisdom?
I'd prefer more recent studies than older ones if possible, as I wouldn't be surprised in changes in culture over time affecting the results. I'm asking this from a white-collar U.S. context, but would love answers that apply to a more general audience.
