There are five iPad and iPhone applications I rely on for my industry updates:
Vogue UK/Vogue Daily News (iPhone)
Net-a-Porter TV (iPad)
Style.com (iPad and iPhone)
F Network (iPad and iPhone)
The Cut (iPad)
The Chanel iPad/iPhone ap is amazing too but obviously it's brand specific.
All of these applications are free, bonus!
The AW fashion weeks in New York, Paris, Milan and London start next month so F Network and Net-a-Porter TV will be off the chain! Get into it.
