I was on the fence between Kara and Jay, until the finale. I think Kara showed her true colors over the incident with the shoes. It turns out that Jay was the only one left with any morals or scruples! Then when she and Wendy got into it, I thought that Kara had sunk almost as low as Wendy.
When the show began, Jay behavior was somewhat immature, and he seemed to be there for the shock value. It was as if he didn't take himself seriously enough to think he'd make it to the final 3 and would probably be eliminated early. When that didn't happen, he seemed to grow up before our eyes as he realized he might actually have enough talent to make it! So when Peter went to visit Jay, it as nice to see Jay relaxed and in a more serious mode....for Jay!
When Peter visited Wendy and Kara...well, that's another story.
I still was waiting to see the collections from each designer, and tried to keep an open mind about it. I didn't care for Kara's, and I thought Wendy's had all been done before. Her pieces were wearable, though, but I didn't think they were very innovative. Jay surprised me with how conservative his collection was, keeping in mind this is from Jay. But I thought he showed the most creativity out of all the designers. I was so happy when he won, since by the finale, he was the only one who had deserved it and who had earned it!
