As you can see, the vest has never been worn.
It is unsold shop stock from the 1940s, and has been in storage at the shop ever since the war.
Size......................Marked as Size W. This is presumably a women's medium size.
Actual bust measurement is 34 inches (unstretched)
Length (shoulder to hem) 33 inches.
Shoulder to shoulder 10 1/2 inches.
This garments was made 70 years ago, to wartime economy standards, and was designed to be hard-wearing and cheap rather than comfortable or beautiful.
It is suitable for ladies or for teenage girls.
UNUSED but SHOP SOILED and with two FLAWS.
This vest is unworn, and in very good condition.
It is unsold shop stock from the 1940s.
It has been properly stored, and is in surprisingly good condition.
It has faded slightly where it was exposed to the light (along the fold lines, as you can see from the photographs).
There are two tiny pinhead-sized holes - one in the front chest, and also a tiny flaw on the edge of one shoulder, at the back.
These appear to be manufacturing flaws (a dropped stitch) rather than later damage, but it is impossible to be certain.
If you wanted to wear the vest, you would need to darn the hole at the front, to make sure it didn't ladder - the shoulder one would probably not need any attention.
In view of its age, if you are thinking of wearing the vest, it will need to be hand-washed or dry-cleaned before use, and treated gently.
