The designers travel to Berlin, Barcelona, London, and Paris to get inspiration for a high-end runway look. They have $1000 and two days (one for planning and one for fabrication) to complete the challenge.

Each of the remaining designers is given six weeks and $9000 to design a 10-piece collection for Fashion Week, including one look made of unconventional materials. In the interim, each gets a special visit in their hometown from Tim Gunn. Back in New York, three designers must choose three of their looks to show as part of a mini-collection in order to secure their spot in the final runway show.

16 new designers arrive in New York with an eye to being named champion of Project Runway's 15th season. At the launch party, they are given their first challenge: use the party's spirit, aura, and vibe as inspiration (and the decorations as materials) for an outfit of their choosing. They have one day to complete their looks.

The designers must create an outfit to flatter all body types, with the winning look to be sold by JustFab.com. They have $150 and one day to complete the challenge.
