This upcoming Spring, Jason Wu and plastic shoe brand Melissa are teaming up to release two exclusive styles. Though both shoes are based on pre-existing Melissa bestsellers — the Ultragirl ballet flat and the Lady Dragon peep-toe slingback — they’re injected with a strong dose of signature Wu: a Miss Wu owl logo bow tops the ballet flats, while a sunburst design culled directly from Wu’s Fall 2011 collection adorns the pumps. “It was really interesting for me to explore design possibilities with plastic,” said Wu of the collaboration. “I wanted to take advantage of the materials I was given, make it all completely functional and waterproof and yet still remain extremely sophisticated.” Both styles will be available in black, burgundy, nude, and transparent gray, and also feature lining printed with pink and black lace. Wu is the first American designer to collaborate with Melissa; Vivienne Westwood, Gareth Pugh, and Jean Paul Gaultier have all previously partnered with the Brazillian shoe brand.
