It was Bill Cosby's connection and those wild collaged sweaters he wore on TV that established Koos' reputation with the rich and famous. More than anyone else Bill Cosby has been a fan and a friend of Koos, inspiring and supporting him through the good and the lean years. Josephine Premice, a singer in the 1980s and a good friend of Koos asked him to make a sweater for a present for Bill Cosby . She took it to the set of the Cosby Show where Bill immediately put in on and wore it for the taping. It was and instantaneous hit. Cosby, in his incredibly generous way began giving his friends presents made by Koos left right and center and the Koos designs became a sensation.
