Mr. Galliano has entered a two-year partnership with the Spanish retailer to “re-author the brand’s archives,” according to an announcement on Tuesday morning. The designer will be “working directly with garments from Zara’s past seasons, deconstructing and reconfiguring them” into new collections that will be released twice a year, beginning in September. That means a line that is not upcycled, not recycled, but also not made from scratch — essentially a wearable look, reinvented.
