A line of clothing
primarily distributed in New York City
The the young man who founded the company later withdrew from society and joined a cult
. I can't remember the name of the cult, but they are known for having long beards, dressing in army green ponchos and riding around on bikes collecting soda cans to redeem the deposit.
Sorry, but I realised the other day that I got the last factoid wrong. The young man who designed the Pervert line of clothing is actually the man being described. Sorry about the mixup.
