A new coat signifies business reverses, whereas an old, shabby or torn coat means prosperity and/or money luck. To hang up a coat indicates favor in the corridors of power. If you helped someone put on a coat, you can expect to be asked for a loan, but if someone helped you with your coat, you will have to borrow. Losing a coat predicts discovery of a false friend; to lend or give one away indicates a widening of your social circle.
