Producers seemed bent on shaking things up in the workroom during Episode 11, which aired last Thursday. It started with a change of models the designers have been using all season. Then came the challenge from hell: designing a head-to-toe sportswear look for Heidi Klum’s line for New Balance.

It was pretty clear how much the designers liked that idea when Heidi came into the workroom for an early critique, with Mondo Guerra rolling his eyes at her comments and Gretchen Jones throwing a fit and a batch of fabric.

The designs in Klum’s collection were simple hoodies and tops, and she didn’t seem to want to stray far, down to using the same bolts of fabric. It’s hard to get designers excited about sportswear, and it seemed that only South embraced the challenge, understanding the need for comfortable chic — second nature in Hawaii where comfort is essential for surviving summer.

Before leaving the workroom, Klum announced that the designers would have to come up with two additional head-to-toe looks and said she’d send in help, which turned out to be the recently eliminated designers, including Ivy Higa. Christopher Collins was third to choose, and picked Ivy. With his name drawn last, South got Michael Drummond, a good designer though not known for his technical abilities, so South said he would have to simplify some steps.

It didn’t take Ivy long to stir up drama by accusing Michael Costello of cheating by using tape in a past challenge. Other designers agreed with her, but because none had complained to producers at the time, Tim Gunn told them it was time to move forward.

On the runway, it was clear that some of the designers just regurgitated designs already in Klum’s collection, which was not a bad idea because Gretchen went the other route, trying to offer pieces absent from Klum’s collection, and ended up on the bottom.

South’s pieces had some very cool graphic lines, and judges noticed his mix of chiffon and jersey fabric, not easy to combine because of the different weights. They praised his designs for style and transparency that made the garments appear light and luxurious.

With comments like that, of course he came out the winner, and although Klum had intended to add only one outfit to her collection, she decided to put all three of his looks into production, available by pre-order on Amazon.com, with delivery in November.

At Andy South Day on Monday at Honolulu Community College, South was asked whether he will be paid for the collection. He said the show’s contract allows contestants to collect royalties, though he is still in talks with New Balance.
