The Vogue facebook page says that the Rachel Comey suit is a copy of the RTW Agave suit and the original pic is really quite nice. I would make the trousrs full length as in the original. Of course the model is 5'10" and a size 8 ... just like me.....not!
The Guy Laroche jacket is a copy of a catwalk version too. They may well have sneaked in a couple of designer copies into the patterns without named designers. I'm thinkiing of a copy of an Alexander McQueen coat they did about a year ago which waa a really nice pattern to make.
