According to this article:
"It's been interesting inviting Barbie into my world and giving her a makeover as part of my spring/summer 2013 collection," Gray told us. "She is so famous; it was fun to give her a Louise Gray twist. It will be really different to anything she has done or been seen in before."
Each look will be available to buy and one of the outfits will be modelled by Barbie herself with the release of a special one-off doll.
