Sounds like part of their "Designer Collaborations" gimmick They've done it with Jean Paul Gaultier and Isaac Mizrahi (Sylvain Sylvain's cousin btw) among others:
Designer Collaborations is an expansion of Target's existing designer fashion program and each collection is available only for a limited time. Designer Collaborations is a unique program that features well-established designers who draw inspiration from a collaborative partner, muse or creative element. It is a new and exciting way of delivering the latest styles to our contemporary female guests at the prices they expect from Target.
