NEW YORK — Laverne and Shirley may have been working girls, but they’d never have been content to blend in with the rest of the assembly line. In fact, off duty, the zany duo made sure they looked picture perfect in collegiate cardigans and circle skirts, lots of plaid and a dash of animal prints for their wilder escapades — involving Lenny and Squiggy, no doubt. Die-hard fans of the show might want to make a bid for Laverne’s pajamas, which will be auctioned on May 24th as part of Christie’s East’s “A Century of Hollywood” auction.
