The September 1955 issue of Vogue is filled with advertisement for luxury coats most notably fur coats. I never realized how prevalent fur was in the 1950s!
Dating Vintage Tip: Browsing vintage advertisements is a fantastic way of dating vintage especially if you know the source of the advertisement! For instance, these vintage coat ads were all featured in 1955, therefore you can gather that coats of similar shape and style were probably popular the year before and the year after. And if the ad/editorial is in VOGUE you can pretty much guarantee similar styles made of less luxurious materials were common several years after. (Remember, Vogue was one of the pioneers of forward thinking fashion... therefore it took awhile for the styles to trickle down to the masses...)
