Lady Gaga on Vogue September 2012 cover

If you can peel your eyes away from the stunning cover — a Mert Alas and Marcus Piggott-lensed portrait of Lady Gaga wearing a gown by Marc Jacobs — there are 916 pages of fashion to behold in Vogue's September 2012 issue.

The issue marks Lady Gaga's second appearance on the cover (she also covered the March 2011 issue) and Vogue's 120th anniversary. It's also the biggest issue in the magazine's history, exceeding the previous record of 840 pages set in September 2007.

The issue will be on newsstands on Aug. 14, and promises a profile on Chelsea Clinton, a story that frames hair as the new makeup, and a look back at the last 120 years of Vogue's history. For now, a look at Gaga's cover — and the magazine's very first cover from 1892 — here in the gallery.
