Besides Ha, top U.S. models Garcelle Beauvais, Abigail Spencer, Aja Naomi King and Jessy Schram also attended the TROA event.

TROA is a fashion house started in 1966 in Seoul by Han’s mother, Troa Cho. Her son, Han Song, gained global recognition for his details and lines that flatter women’s figures. He was named Fashion Designer of the Year by the Seoul Fashion Council and designed the national uniforms for the Asia Games.

In fall 2013, TROA debuted its jeans exclusively at Barneys in New York and Japan, and at Colette in Paris.
