I have a modified Costumebase Boba Fett flightsuit. Its grey in color, so its great for ROTJ Fett. I've shortened the upper sleeves as well as repositioned the thigh and knee pockets to be more accurate. Its an XXL (Asian size); I have a 40" chest and 38" waist and it fines fine with slightly additional room for larger builds. USD$65 shipped.
