On her arrival at Narita Airport, Tokyo, on 8 May 2012, Lady Gaga wore a Versace trench from the fall-winter 2012-2013 collection. She was in the city for the Born This Way Ball, a performance in which she and her dancers wear some specially-designed Versace outfits.
In the photo below, a shot from the Versace fall-winter 2012 runway show with the same garment.
The Versace trench coat is entirely covered in Swarovski crystals. Below, the complete photo of the Lady.
