Fashion models aren’t prized for their braininess — or their literary pursuits. But that hasn’t stopped this genetically blessed crowd from expanding its brand with tell-alls, novels and self-help books. Iman and Cindy Crawford have makeup guides, Christy Turlington put out a book on yoga, and reality TV queen Janice Dickenson has spilled three tomes on her sordid, affair-strewn life.

Now three more models — two marquee names from the ’80s and one modern-day ingenue — are promising juicy tales of triumph and humiliation inside the chaotic modeling industry. Here’s how they measure up.

“Sex, Love and Fashion” By Bruce Hulse (Harmony Books, $23.95) The hype: Tell-all memoir from one of the “top 10 male models of all time.” The reality: Exhaustively detailed chronicle (it has an index!) of a relative unknown. The scribe: An ’80s model more famous for bedding supermodels — Andie MacDowell, Paulina Porizkova, Elle Macpherson, Tatjana Patitz —than gracing the cover of GQ. Why he wrote it: “To talk about my life in the wild and exciting fashion world and also to explore my journey to find true love and happiness.” Literary prowess: Cliche central. “I let the sea wash over me like a baptism.” Its charms: Supermodel dirt. A tryst with Paulina Porizkova was “like a professional wrestling match.” Trying to remain, um, calm, when Elle Macpherson stripped down was challenging. Its defects: Chapters devoted to his pre-model life are as titillating as a tax appointment. Lesson learned: It takes a hunk to land a supermodel. Bottom line: Twice as long as it needs to be, but the gossip factor — Naomi Campbell was once sweet and innocent? — will keep fashion fiends turning pages. “This Year’s Model” By Carol Alt (Avon A, $13.95) The hype: Fictional roman a clef for teens and 20-somethings about breaking into the rough-and-tumble modeling world. The reality: True to billing. Follows the lightning-fast ascent of a teen discovered by a photographer at her waitressing job. The scribe: Cat-eyed ’80s supermodel-turned-raw food fanatic most famous for gracing the cover of Sports Illustrated’s 1982 Swimsuit Issue. Why she wrote it: “To teach without someone realizing they are being taught.” Literary prowess: Acceptable, despite irritating inner-dialogue (“Who knew designers were doing vodka now?”) Its charms: Realistic fashion world observations — Teen Vogue editor Amy Astley dresses like a schoolgirl; designer Randolph Duke attempts a comeback with cowboy pants and bolero vests. Its defects: Sleazy guys. Weight-watching model bookers. Cocaine-pushing British rock stars. In other words, realistic fashion world observations. Lessons learned: Avoid photographers looking to “build their book” and geriatric Italian playboys bearing diamond tennis bracelets. Oh, and stop eating. Bottom line: “The Devil Wears Prada” of the modeling industry — a quick, guilty-pleasure read bound to score big with the “America’s Next Top Model” crowd.

“Model” By Cheryl Diamond (Simon Pulse, $23.95) The hype: The “triumphant rise, disastrous fall and phoenix-like comeback” of a teen model. The reality: Job-by-job story of a street-savvy young woman navigating New York’s cutthroat modeling world. The scribe: One of a million worker-bee models earning her keep working hair trade shows, catalog jobs and small-time advertising gigs. Why she wrote it: “Because modeling really is bizarre.” Literary prowess: Written for teens with language as basic as a tank top, with none of the juicy stuff about modeling’s real pitfalls. Its charms: An alien could read this and start going on go-sees. The industry is explained ad nauseam. (“Many agencies don’t send a booker out to look at models, relying instead on the impeccable judgment of a slightly daffy receptionist.”) Its defects: Crazy slow at times — but we’re not 14 and Agyness Deyn-obsessed. Lessons learned: When your long blond hair is your fortune, don’t let anyone dye it tangerine orange. Bottom line: A decent read if you’re curious about life as a model when you’re not Gisele Bundchen.
