Muzungu Sisters - Make Muzungu Sisters's cloud-grey Shereen kaftan one of the first things you pack for a hot-weather getaway. It's handmade by a skilled artisan from featherweight cotton-poplin, and shaped to a simple shirt-style silhouette with a collarless neckline and side-slit hem. Consider it the perfect backdrop for statement accessories – think a chunky necklace and rainbow-hued belt.
