You are looking at a nice Vietnam era U.S. Navy tailor made uniform. Has a Petty Officer 2nd class Machinist Mate rank patch, 4 ribbons to the chest, and a ship tab to the shoulder; U.S.S. Charles F. Adams. Button cuffs, zipper to the side. No size tags. Shoulder seam to shoulder seam measures about 16 1/2 inches across. Armpit seam to the end of the cuff measures about 20 inches long. From the top of the neck area to the end of the waist measures about 22 inches long. No holes or stains that I can find. Has a name to the inside. Nice example. See photos for more details.
