Stella McCartney went wild for pre-fall, using feather, lizard, and zebra prints for short dresses and jumpsuits. A knit minidress featured a prowling leopard. Her exploration of architectural lines, as on a round-sleeved and grommeted bolero or pieced jersey separates, looked strong, if primarily destined for magazine spreads. A sporty, oversize black silk topper and other slouchy outerwear pieces, on the other hand, are sure to be hits at retail.
