The last day of Milan Fashion Week dawned Sunday with fanciful and joyous confections shown beneath an arch of iridescent flowers by emerging designer Susan Fang, whose latest collection was supported by Dolce & Gabbana. Fang said she was inspired by her mother’s happy memories growing up in rural China, incorporating bucolic scenes reproduced from her mother’s paintings. Dresses of strips of colorful fabric exuded what Fang called “a bouncy feeling of happiness.”
