New Fashion Illustration contains interviews with 30 fashion designers based all over the world, with a selected showcase of their work.
Each designer has a 1-page interview where they write in first person their creative inspiration and love for fashion design. The many designs included are created from a wide variety of medium including digital, collage, watercolour, vector, oil on canvas etc. There's a lot of different artistic style to look at.
I would say this is more of an art book rather than fashion design book.
