See Reuters, Palin hair big with partygoers, NY's Orthodox Jews,
...in an Orthodox Jewish neighborhood in Brooklyn, the look has become popular among some Orthodox Jewish women, who buy wigs to cover their hair for religious reasons. Made of human hair, the Palin-style wigs cost $695 or more. ...
Shlomo Klein, an Orthodox Jew and vice president of wig maker Georgie Wigs, said he sold more than 50 of the "Sarah P" wigs across America in recent weeks to women wanting wigs either for medical or religious reasons. ...
The Palin look had replaced previous popular looks among Orthodox Jewish women such as Victoria Beckham's "Posh Spice" look and Jennifer Aniston's "Friends" cut, he said. ...
