Hyosung took on the 'energetic' concept for 'Yes' new 2013 fall collection by becoming a sexy cowgirl. With the fall season coming, she also busted out the long-sleeves, adding a bit of a cover up for her lingerie looks.

A 'Yes' marketing representative commented, "Hyosung's unique, lovable energy perfectly coincides with 'Yes' concept. This fall, 'Yes' and Hyosung's own colors and styles will appeal to our target customers in their 20s."
