If you remember from the last episode, the judges only *guaranteed* three spots for Fashion Week, so the designers had to show the judges a two-look preview to decide who was officially moving forward. In the past they have done this with three-look previews, and I think that's a better system to allow the designers to showcase a beginning, middle, and end to their collections. A lot of them struggled with choosing two looks that fully represented every aspect of their collections, and it didn't feel like a very fair system.
But hey, they didn't ask me.
All that said, the judges have a tendency to do the opposite of what anyone expects, so WE SHALL SEE!!
