When Lady Gaga puts on a dress, it transforms from merely a dress into an absolute fashion statement. So when Lady Gaga stepped out wearing Yves Saint Laurent, hopping out of an airplane in Sydney, it was instant publicity for the brand.
Not that Yves Saint Laurent needs publicity anyway. But it is always nice to see Lady Gaga wearing something from a fashion designer. This particular dress is from Yves Saint Laurent Edition Soir 2011 collection.
