here's a definition found by google: Clothing Line Look Books are not the same as line sheets because they don’t have specifications usually and prices or sizes aren’t included. Most look books include photos of an upcoming line usually on models and are coordinated with other pieces of the line. Photo shoot pictures are sometimes used in look books. They don’t have to be very expensive you can easily create one by having professional photos taken of your line or take them yourself and organize them into a portfolio so to speak of your upcoming spring/fall line. A binder or folder os some kind would do just fine. Here is an example of an online look book by SNAC clothing or have a look at The Hundreds look book here. Even with some companies taking advantage of using look books I wouldn’t say it is a must have when starting a clothing line. from: http://www.dobizo.com/daily-definition/dai...tion-look-book/ i say it's more about presenting the clothes than focusing on the model. by the way, many thanks for the great new pics!
