Vintage children's nylon vest. Made in England, in the late 1960s or early 1970s, but never used (unsold shop stock).
Marked (very unhelpfully) as "SMALL", so please check the measurements are right for what you need. It looks ROUGHLY age 11-12.
Chest measurement is 21 inches unstretched, 30 inches fully stretched.
Shoulder to hem measurement is 24 inches (this is a bit longer than most modern vests).
Condition: Vintage clothing, about half a century old, but never used and still in perfect condition, except that the removable size sticker is damaged. Please remember that this is an old garment, and is not likely to last long in normal use, though it might be ideal as part of a genuine 1970s costume or display.
