Found this a while ago and don't know what I have on my hands:
Mario Ferretti suit made with 100% Loro Piana New Zealand Merino Super 130s wool. Tagged size 52/42, jacket is 3 button, dual vent, flap pockets. One vent is still basted shut.
Pants are single pleated, uncuffed, lined to knees, rubber strip on inside of waistband. Looks absolutely brand new, came on a quality Mario Ferretti hanger.
