From a few simple lines, Tibi designer Amy Smilovic has created a minimalist, modernist look in bright white. Rather than looking dated, the short sleeves and longer hemline of this Tibi dress have a decidedly future-facing outlook. Knit. Crew neckline; short sleeves. Below-the-knee pencil skirt. Sheath silhouette. Back zip. Polyester/spandex. Imported.
