These guys are very entertaining. At the bottom of the home page they have indexes for links. Under Project Runway, there is a drop-down box called "Finale Collections". You can then select Season 7 Finale Collections.

I saw the Christian Siriano show, too. I really liked it. It was really interesting and I thought a lot of his clothes were very cute. (And I wasn't a Christian fanatic when he was actually on PR.)
