I have been pining for Arthur Elgort's Models Manual for months now.  I received it as a Christmas gift this year and have been absolutely dying over it!  It is basically the fashion world / industry as seen and described by the models themselves.  Famous fashion photographer Arthur Elgort complied his favorite candid (and not) photos of models he's captured over the years, and interviewed the models about their time in the industry.  It is fascinating and beautiful.  I've learned so much through the images alone.  The bottom photo is a little snippet he added in of the legendary Karl Lagerfeld.  I highly recommend purchasing this whether you're studying fashion like me, or simply enjoy it as a hobby!
