Cosmopolitan patterns are not often found, probably because it appears to have had a short run as a pattern company. Cosmopolitan Fashion Model Company’s patterns first appeared in newspapers in May, 1895. The ad was addressed specifically to “ladies”, but they did offer at least some men’s patterns, as seen here. They were advertised for a “uniform price” of 15 cents each. An ad in September stated that “to make them more well known”, they offered a pattern for 15 cents, postage paid. That ad states that the retail price was normally 20-40 cents, but that they were again selling them for a uniform 15 cents. By far, the majority of newspaper ads of 1895 were seen in California.
1896 saw ads spread nationwide, indicating that they had indeed gotten the word out about their patterns. Pricing remained the same.
1897 saw a significantly fewer amount of ads, indicating perhaps that the company had gone into a bit of a slump, but 1898 saw an explosion of ads, so perhaps this was not the case. Perhaps they did so well in 1897 that they didn’t need to advertise. It’s not clear. One 1898 ad stated they were selling for 10 and 15 cents but were “just as good as 25 cent patterns.” Not the best marketing ploy, I think. Somewhere between 1897 and 1898, the name was shortened to simply Cosmopolitan Patterns in ads, though I believe that the packaging still said Cosmopolitan Fashion Model Co, as one I have from after 1900 has this still printed on the envelope.
1902 ads from Albuquerque indicate pricing of 10 cents, but no reference is found indicating what the “retail” (printed on the package) price was. By then, their slogan had become “none higher, none better.” By May of that year, some ads show prices of 9 cents, showing that perhaps they wanted to live by their slogan. 1904 found pricing at 10 cents. Continuing to 1907, the ad stated that Cosmopolitan was the only “10 cent seam allowance pattern.”
1908 saw some stores advertising free Cosmopolitan patterns with a purchase, and in 1909, many stores advertised that they were no longer carrying Cosmopolitan patterns, but had taken on contracts with McCall. Some stores were still advertising Cosmopolitan, but at 1 cent. The company was definitely in trouble. By 1910, they were no longer advertised at all.
Perhaps Cosmopolitan was bought by McCall, but I can’t find evidence of that. Indications are they they only published womens’ patterns, but if I am wrong about that, please do let me know. Cosmopolitan did well for a few years, in a very competitive pattern market. It may be that undercutting their prices meant they paid a heavy price, but they don’t seem to have caught on, and their marketing slogans definitely needed improvement. One thing to note though is that they always sold for less than the printed price, so price on the envelope will not help in dating them. You will have to study the style in order to come up with an accurate date, but it should always be between 1895 to 1909.
