Vintage work white uniform for a United States Navy Aviation Machinist's Mate. There is the jumper with neck flap and a pair of trousers. We're not sure of the exact vintage or of this uniform.
The uniform jumper measures 20" long on the arm (armpit to cuff), 42" around the chest (under the arms), 18" across the shoulders on the back and 25" long (from the base of the neck flap to the bottom in the back).
The pair of pants measures 30" around the waist and 30" long on the inseam. This uniform has areas of discoloration.
