Hey there!
First, we have to determine that "dressing" means really working harder and adopting a new set of ideals.
If you "dress" for the position you have, it means you're content and don't want to go higher.
However, if there's a position you want and don't have, you should be working hard to prepare and "dress" for it.
Hope this helps!
