Murray Shirtdress in Black Heart Cutout CottonUsing her signature "Heart Swiss Cheese" fabric from the Spring 14 collection, Rachel Antonoff has created the perfect LBND (little black nursing dress) for the summer. Made of soft, airy cotton in an easy and flattering fit, this shirtdress makes getting dressed a breeze. Add a pop of color in the form of a belt or bag with a flat sandal for daytime errands with the kiddos. Throw on a heel for date night or add a cardi or blazer for an office look.
