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.
