This week's challenge, informs La Klum cheerfully, has to do with going back to school to further their education.

This week's guest judge is model and designer Erin Wasson. La Klum herself is in New Balance along with a spangly black jumpsuit. And the show begins!

Heidi presents their next challenge by saying that they are designing for a very important client who knows a lot about fashion. Enter Nina Garcia.

This week's challenge is delivered to the group by Heidi on stilts. "For the next challenge we want you to think big," she smiles.

Tim meets the gang outside Petland Discounts to advise them that this is the Unconventional Challenge: they are to design a garment using items purchased in the store.

We're back here once again, watching Heidi, Nina, and Michael Kors blithely destroy young dreams.
