The members of Girls' Generation have gathered together for the first time in a long time to celebrate their 17th anniversary and member Tiffany's birthday.

On the 5th, Seohyun shared a group photo of the members of Girls' Generation, showing off their friendship. All of the members are dressed in white, with only singer Sunny unable to attend, so Seohyun composited them together to make the group look complete. The youngest member of Girls' Generation also revealed how close the group has become, saying, "That's right, I'm going to talk to her."

Singer Yuri also posted a video on her channel on the 5th to celebrate the 17th anniversary of her debut. The video began with the subtitle, "Today is the long-awaited Tiffany's birthday party. Yuri emphasised the dress code by showing off her white outfit in a mirror shot. Arriving at the party venue, Kwon Yuri showed off the food and the sprawling outdoor pool and thanked Tiffany, saying, "This is Fanny's birthday party, prepared by Fanny."

The girls' outfits were also a hot topic of discussion. Tiffany wore a ballerina-inspired outfit, but Tiffany herself said it was inspired by her Inside Out character "Anxiety". Hyoyeon and Seohyun also arrived, and the members, except for Yuri, wore outfits like "princesses at a party. When Sooyoung pointed the camera at Yuri and asked, "What is this place?" Yuri replied, "I look like the only one who came in shape, didn't I misunderstand the dress code?" and struck a muscle queen pose.

As Yuri was being criticised for her outfit, Taeyeon arrived. Taeyeon also wore a princess-like outfit, but the members had already voted for Hyoyeon as the best dressed. Hyoyeon drew attention to her side-slit dress. Last but not least, YoonA arrived. With Sunny out of the country, Tiffany's birthday party and 17th debut anniversary party began. The members brought Tiffany a birthday present, but Hyoyeon thought it was Girls' Generation's 17th anniversary party and said that she forgot to bring a present, causing laughter.

Meanwhile, Girls' Generation consisted of Taeyeon, Sunny Tiffany, Hyoyeon, Yuri, Sooyoung, YoonA, and Seohyun.
