CHAOS THEORY: Heidi isn’t one of them. In Wolfgang Joop’s newest book,“Dresscode,” due out April 20 in Germany, the Potsdam-based designer presents a personal look at 12 women he considers “style icons between cult and chaos.“

Written and illustrated in between his frequent trips to Los Angeles for the filming of Germany’s “Next Top Model” with Frau Klum, the book unfurls a diverse dozen with Diana Vreeland serving as godmother to the crew. They are: Caroline Roitfeld, Alexa Chung, Lena Dunham, Virginie & Claire Courtin-Clarins, Iris Apfel, Lauren Santo Domingo, Diane Keaton, Caroline de Maigret, Tilda Swinton, Rihanna, Chloë Sevigny and Kate Middleton, whom he dubs the “No Drama Queen.”

The 250-page book, published by Gräfe und Unzer, is not big on styling tips, instead advising women to make the best of their type employing “sovereignty and chutzpah.” It’s also meant to amuse, each portrait sprinkled with bon mots and the subject’s presumed Do’s and Don’ts, such as Dunham’s, “avoid everything in styling that ends in esque: clownesque, burleque, grotesque, carnivalesque;” or Roitfeld’s “emphasize supposed problem zones. That makes you interesting.“ Not to mention “Wolfy’s Fashion Glossary“ of catchwords which appears at the end of each woman’s chapter, and will probably cause headaches for whoever translates the book into English. An English edition, the publishers said, is planned for the not too distant future.
