When fashion magazines first moved to the web they basically just duplicated their print versions online. Bravo to Vogue for finally showcasing different ways to represent the magazine.
The archive includes every issue and every page of Vogue since 1892. This is a wonderful idea, but a bit pricey for the casual user.
For free you can browse Voguepedia. It is filled with information like backgrounds on designers, editors, models and photographers.
Vogue Original Shorts
My favorite section of Vogue online is their videos, particularly the original shorts. I love the way they poke fun at fashion. (Lena Dunham and Hamish Bowles “Cover Girl” is great).
