Decades of being in the fashion industry has given Jeffrey Banks fame and fodder, and soon he will be sharing some of that intel in the new book “Storyteller: Tales From a Fashion Insider.”

Inspired in part by advising his good friend Stan Herman about photos for his Pointed Leaf Press-published memoir “Uncross Your Legs: A Life in Fashion,” Banks started working on his own tome last summer. That turnaround time was accelerated by the designer’s sharp memory. He said, “People are always astounded that I can remember memories from 30 to 40 years ago — what you were wearing, what music was playing, where we had lunch, what time of day it was and that kind of thing.”

The designer said he was also motivated to wrap up the book quickly so that his 104-year-old mother Eleanor has the chance to read it “before she leaves this earth.” The title comes from the fact that people routinely praise Banks for his lively storytelling. How to begin? Banks started with why he wanted to become a designer at the age of 10, which is when he sketched an Easter outfit for his mother, picked out the fabrics, “very thoughtfully chose” what accessories to wear with it and went to the dressmaker with her.

As much as he loved art and drawing, Banks said he had read that so many artists did not achieve success or fame until after they died. Not interested in taking that career path, he said he considered fashion design to be immediate gratification, “Somebody either likes what you did or they didn’t. It either sells or it doesn’t,” Banks said.

His tome traces his rise from Ralph Lauren intern to Parsons School of Design graduate and starting his own namesake company. Along with having his designs shot by photographers such as Bruce Weber and Richard Avedon, Banks shares tales about Lauren, Calvin Klein, Audrey Hepburn, Bobby Short and Barbra Streisand.

The most revelatory part of writing the memoir was realizing what a perfectionist he is. Recalling how his late father, a cartographer by profession, brought him to tears at the age of five by instructing him for 90 minutes how to tie his shoes properly, Banks said, “I wanted to run as far away from that as possible. But when it comes to my work and my craft, I am a perfectionist and exacting. I guess I am just like him in that respect.”

In 1977 at the age of 23, Banks won his first Coty award, a precursor to what is now the CFDA awards, for Outstanding Fur Design with Alixandre Furs. Banks also was nominated for the Menswear Designer of the Year, despite the fact that he had only been in business for a year and more established names like Alexander Julian were in-the-running. Banks first learned of his Coty Award win during a buying appointment with Bergdorf Goodman and Neiman Marcus, which at that time sold more furs than any other store in America. (Furs were so popular the luxury store had a separate holiday catalogue devoted to furs.) Upon arrival, Banks was greeted with congratulations, since his win had been reported in that day’s New York Times.

In 1982, Banks took home the Menswear Designer of the Year at the Coty Awards. As for his lasting contribution to fashion, Banks said, “Even though it wasn’t what I set out to do, the books that I’ve written have been able to capture history, which was always one of my favorite subjects.” In addition to three biographies, “Perry Ellis: An American Original,” “Norrell: Master of American Fashion” and “Patricia Underwood: The Way You Wear Your Hat,” he cowrote “Preppy: Cultivating Ivy Style” and “Tartan: Romancing the Plaid.” Banks also pitched in on Robert Bryan’s “American Fashion Menswear.” More recently, he penned the introduction for “Audrey Hepburn: A Life of Beautiful Uncertainty.”

Busy planning a book tour that will include stops in Chicago, Austin, Dallas and probably Palm Springs, Calif., Banks is also at work on the next season for his home decor collection. “I haven’t had a chance to celebrate,” he said, referring to the tome, which will be released Oct. 14. Readers can glean some insights, when he joins his friend Fern Mallis at 92NY on Sept. 18 for a Q&A.
