Celine

Phoebe Philo's Resort 2013 collection for Céline showcased what the house does best: laser-focused, impeccably tailored separates with undeniable graphic appeal. Crisp, wide-legged trousers were a focus this season: some met the ground with a band of color, while others had tuxedo stripes in bright hues. Philo also turned out a few great pieces of outerwear, such as a leopard coat with blue leather sleeves and shoulders and a burgundy coat with multiple horizontal zippers that allow the wearer to create different lengths. Juxtaposed against the defined edges and clean lines were silk scarves tied at the neck, and bias-cut crepe tops draped to create a languid gathering of fabric at the neck.
