On the 49th Taxpayers Day in Korea last month, it was announced that SNSD‘s Yoona and actor Song Seung Hun were awarded with the Model Taxpayer Award. On the morning of April 23, the ceremony was held to officially appoint the pair as ambassadors of the Internal Revenue Service. For the event, Yoona looked demure in a Valentino Leather Collar Dress ($4390). The vibrant red-orange dress is made of a blend of wool and silk. It also features a detachable leather collar with a funky, colorful floral motif. Considering her boyfriend, Lee Seung Gi, has previously been awarded with the President’s Award for Savings, it shows that they are certainly a fiscally responsible couple!
