Katy Perry wears an Erin by Erin Fetherston dress at the 'Part of Me' press conference

Ahead of the first premiere of her 3D documentary 'Part of Me' to be held in LA, superstar Katy Perry held a press conference at the Four Seasons to promote her latest venture. She looked gorgeous in an Erin by Erin Fetherston dress, which was a pink ombre colour with little flutter sleeves, and beautiful petal details down the front. The dress was paired with a pair of nude pumps and a pink lip colour. Katy's purple hair stole the show along with some statement pieces of bling rings. The LA premiere of 'Part of Me' is to be held on the 26th of June, followed by a London premiere on 3rd July.
