This is a Ben Zuckerman jacket, once paired with a skirt, in a gorgeous red. The jacket is double breasted, with leather-look buttons, and interesting seaming around the neck, jacket opening and bottom of the jacket.
The jacket has 4 pockets and is made of the most incredible material- a single colour tweed that gives the appearance of a window-pane check. Amazing!

This is a Ben Zuckerman cocktail coat in the heaviest, richest green velvet. It is double breasted and has the classic Zuckerman jewelled buttons that make the coat out of the ordinary. I suspect this coat is made of silk velvet, which is simply silk woven into a velvet which leads to an incredibly soft and luxurious velvet, with a very high price tag. It is almost impossible to find 100% silk velvet today but it was used more frequently in the past.

This is a really interesting ad from The New Yorker, 1957.
The ad is for Bigelow Rugs and Carpets and features a model wearing a Ben Zuckerman suit and a Lilly Dache hat. The suit is navy, with a calf length skirt and a jacket that nips slightly at the waist and has 3/4 length sleeves. The model is perfectly accessorized with a mink hat and matching stole as well as pearl earrings, navy court shoe and tan gloves.
It is hard to imagine anyone nowadays getting this dressed up to clean the carpets. Even in the 1950's I doubt many woman would don this outfit to clean, however they still would have likely worn a dress and been more put together than we would expect someone doing housework to be.

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.
