Celebrate Chuseok with Girls' Generation this week!

Since it's a special holiday in South Korea this week, not much has happened with Taeyeon, Jessica, Sunny, Tiffany, Hyoyeon, Yuri, Sooyoung, Yoona, and Seohyun.

However there was the Samantha Thavasa launch event they attended on Wednesday, September 18, 2013.

The girls donned the first line of jeans released by the Japanese fashion brand. Following their appearance was an exclusive performance of "Galaxy Supernova" and "Gee" for 200 fans in honor of their collaboration for their new Japanese single.

As for the special Korean Thanksgiving holiday known as Chuseok, the members of Girls' Generation took the time to update various social media sites to greet fans.

Check out what some of the girls posted on either their respected SNS accounts or the Girls' Generation official homepage!
