Postwar children pack large underclothes (8)
I believe the answer is:
bloomers
This might be a double definition.
'postwar children pack' is the first definition.
The answer and definition can be both man-made objects as well as being singular nouns.
Maybe they are linked in a way I don't understand?
'large underclothes' is the second definition.
The definition and answer can be both man-made objects as well as being singular nouns.
Perhaps there's an association between them I don't understand?
Can you help me to learn more?
(Other definitions for bloomers that I've seen before include "Boobs" , "rational dress" , "Embarrassing mistakes" , "of bakers, gardeners and > underwear suppliers?" , "Bread - mistakes - underwear" .)
