Project Runway Allstars Mondo Guerra, Viktor Luna and Seth Aaron showed off their Spring 2016 collections to a packed audience at FashionNXT's 2015 finale show.

Mondo Guerra's monochromatic collection was a unique spin on the white minimalism that showed up again and again at this year's FashioNXT. He shaped soft and hard plastics into translucent, interlocking triangle patterns that looked inspired by paper planes. The entirely white collection of dresses and two menswear pieces viewed like an unlikely runway marriage of classic yacht wear and BDSM science fiction battle gear, heavy with synthetic fabrics, mesh and sheer materials.

Viktor Luna's collection takes the battle theme in a more literal direction, transforming his models into cyborg Valkyries in gold and silver lamé, leather, plastic and synthetics. Luna's collection of separates, dresses and coats incorporated leather breastplates and chainmail-style, metallic fabrics in purples and grays, making it the most unique and visually striking collection of the entire show.

Seth Aaron brought things things back to Earth to close the show with his classic menswear-inspired collection titled "Thoroughfare." Working with more traditional fabrics than the space-age materials of his predecessors, Aaron's mostly black-and-white collection of dresses, outerwear, jumpsuits and gowns was a modern spin on classical Hollywood style that didn't lean on sentimentalism for effect.
