SISTAR is starting off Chuseok celebrations a little early. Every year for this festival, celebrities dress up in colorful hanbok and release the photos, as a gesture of gratitude for their fans' continued support. The postures may look a little strange in the photos; Koreans go through a specific set of motions for a special bow called Saebae, a traditional greeting for special holidays and occasions. SISTAR wrote, "We hope your fall is enriched with happiness! Eat a lot of songpyun (traditional rice cake)!" After performing at "Hallyu Music Festival" in Japan on the 20th, the girls will split up for a short while to see their families during the holiday. They're surely having a great year so far!
