We've witnessed "Mad Men's" world of coiffed women, dapper but philandering men and retro fashions strike a serious sartorial chord.

And StyleList has previously reported on fashion retailers Banana Republic and Brooks Brothers collaborating with AMC's hit series on limited edition lines.

But now, small vintage shops are benefiting from the latest trend: "Mad Men"-themed parties, reports Reuters.

"I've been selling a lot of looks from the late 1950's and 1960's with all these 'Mad Men' parties going on," Lillyan Peditto, owner of New York City's vintage shop The Family Jewels, told the news site.

Why the sudden urge for retro costume parties, and before Halloween?

Sarah Capozzi, a clinical social worker from New Hampshire, who is organizing her own "Mad Men"-insired fête, gave the source her theory:

"[It's] a chance to step outside of ourselves and come to a place in society where people answer the phone politely and wear fedoras to work or gloves while driving ... it's civilized!"
