Adjustment to your suit after promotion to manager?

I have been recently promoted from senior consultant to manager and will be leading a team of 12 people. What changes should i make regarding dresscode, suit, ties etc. to show dominance or just to get more respect in general? So far i am wearing a navy blue suit with a red or dark blue tie (without patterns). Anything else you guys would wear in a managing position to be more distinguishable from junior people?
