An undated ad, likely from the 1940's, featuring a Zuckerman and Kraus suit. It has the larger shoulders that is typical from an early 1940's suit, with a knee length skirt.
While formal rationing of clothing was never put into place in the United States (unlike in Britain, where clothing was strictly limited and all extraneous trims were forbidden) during World War II, clothing manufacturers still tried to limit waste and fashions changed more slowly as it was seen as unpatriotic to be wasteful. This suit jacket has only 3 buttons and the skirt is very plain, which would not date as quickly.
