Steve Jobs is known for 
many things -- the Apple II, the Macintosh, Pixar, the iMac, iTunes, iPod, iPhone and iPad.
 He is also known for his signature black turtleneck, Levi's jeans and gray New Balance sneakers.
 But just how Jobs arrived at that look after wearing 
neckties, 
bowties, 
vests and jeans covered in 
patches, isn't as known.
 That will change, however, with the release of Walter Isaacson's  highly anticipated authorized biography on the Apple co-founder, titled  simply "
Steve Jobs."
 The book -- the product of more than 
two years' worth of interviews  with Jobs' family, friends, colleagues and rivals -- includes details  on how Jobs' look came about. That passage on was published Tuesday by  the website 
Gawker in an excerpt from Isaacson's book.
 The book also includes interviews that took place just weeks before Jobs' death Oct. 5.
 From Issacson's book, as reported by Gawker:
 
On a trip to Japan in the early 1980s, Jobs asked Sony's chairman  Akio Morita why everyone in the company's factories wore uniforms. He  told Jobs that after the war, no one had any clothes, and companies like  Sony had to give their workers something to wear each day. Over the  years, the uniforms developed their own signatures styles, especially at  companies such as Sony, and it became a way of bonding workers to the  company. "I decided that I wanted that type of bonding for Apple," Jobs  recalled.
 Sony, with its appreciation for style, had gotten the famous designer  Issey Miyake to create its uniform. It was a jacket made of rip-stop  nylon with sleeves that could unzip to make it a vest. So Jobs called  Issey Miyake and asked him to design a vest for Apple, Jobs recalled, "I  came back with some samples and told everyone it would great if we  would all wear these vests. Oh man, did I get booed off the stage.  Everybody hated the idea."
 In the process, however, he became friends with Miyake and would  visit him regularly. He also came to like the idea of having a uniform  for himself, both because of its daily convenience (the rationale he  claimed) and its ability to convey a signature style. "So I asked Issey  to make me some of his black turtlenecks that I liked, and he made me  like a hundred of them." Jobs noticed my surprise when he told this  story, so he showed them stacked up in the closet. "That's what I wear,"  he said. "I have enough to last for the rest of my life."
