The six remaining designers create complementary stage looks for country rock crossover group, The Band Perry, for an upcoming Nashville show. Making menswear for brothers Neil and Reid Perry throws some of the designers into a panic and tests who can adapt to an unfamiliar task.

The designers create looks inspired by old Hollywood glamour for Khloé Kardashian to wear at a Grammy Awards after-party. For the first time throughout the construction process, the designers receive no direction from the mentors. Instead, they must critique each other's work and use the lessons they've learned so far to guide themselves. Recording artist Ne-Yo is guest mentor.

The remaining four designers must create complementary looks for power couple Naya Rivera and Big Sean for his record release party. She wants an exposed midriff and asks that Sean's style move beyond his typical white t-shirt and jeans. But how will the designers create two looks in so little time? Help comes in the form of some very special project assistants.
