During her three-year tenure in Balenciaga's creative department, Laura Tanzer had a front-row seat to the time-honored tradition of haute couture craftsmanship. Now, in partnership with her wife, the former professional tennis player Jessica Simpson, the Zurich-based Central Saint Martins graduate has extended that sartorial savoir faire to the home with Millaux, a new line of bedclothes. "We take such time to decide what to wear, but a lot of people overlook what they put on their beds," says Simpson. Created in heritage Italian and Portuguese ateliers, the made-to-order range combines historical artistry with a playful opulence inspired by centuries-old chateaus. The initial offering includes jumbo-striped European flax linen sheets, jewel-toned Egyptian cotton sateen pillowcases and 610-thread-count orchid-dotted duvet covers dreamed up by the textile designer Fiona Blakeman, who has previously worked with the fashion designers Phoebe Philo and Grace Wales Bonner. Much like a collection of clothes, the 20 debut pieces, each of which is sold individually, are meant to be mixed and matched. From $190, millaux.com.
