Girls' Generation kicked off their world tour in dramatic style over the weekend at the Seoul Olympic Gymnasium. 

The '2013 Girls' Generation World Tour - Girls & Peace' is their first world tour, and leader Taeyeon was quite proud to hold a world tour as she stated, "Every time we had a concert, we always said we wanted a world tour. We're honored to finally perform under the title of a world tour."

The girls performed all of their numerous hits, including, "Gee", "Genie", "I Got A Boy", as well as their Japanese hits such as "Paparazzi", "Flower Power", and even "Love & Girls", as Taeyeon had promised. 

The girls showed off a variety of forms and concepts, from cute to sexy and innocent to mature all at once. They were cute little sisters with a pure white one piece for one performance and then they would immediately transform to the sexy noona next door in red dresses showcasing their beautiful legs.

Many fans packed the Olympic Gymnasium for two nights to support the girls throughout the concert. The fans became the loudest when the girls shouted, "Right now is Girls' Generation. It'll be Girls' Generation in the future, and forever!"
