Watch Project Runway: Threads

The designers must create a standout final look for their runway show.

This week's designers are serious, focused and competitive. They all have their eye on the twenty-five thousand dollar prize package and are determined to take home the win. They are excited to create a cover-worthy look for Seventeen magazine, but not always thrilled with host Vanessa who seems to interrupt them with twist after twist.

The designers compete in a monster mash up.

Three news designers join Project Runway: Threads to show us their take on the future of fashion. They all have impressive talent, but when they are the boss, not only of their adult assistant, but also of a Project Runway alumni does one of them take it too far? Does power get the best of one of the designers? Good boss or power hungry? You decide. Vanessa Simmons hosts. She is joined by judges Christian Siriano and YouTube sensation Ingrid Nilsen.

Actress and singer Zendaya guest judges and is impressed by the designs of Matt, Brianna and Claire.

Relationships are put to the test for the three teen designers and their adult assistants.

In just one day three fresh, new teen fashion designers create designs worthy of runways around the world. Just when this spunky and talented group of teens and their adult assistants feel that they have it all under control, the fashion roller coaster takes off. They are talented well beyond their years, but can they handle the pressure when time is not on their side? Vanessa Simmons hosts. She is joined by judges Christian Siriano and YouTube sensation Ingrid Nilsen.

In the series premiere, Kelly Osbourne and Jaime King join Project Runway: Threads as three teen fashion prodigies are challenged to create a red carpet look that is not what it seems.
