TaeTiSeo (Taeyeon, Tiffany, and Seohyun) treated SONE who are patiently waiting for their comeback with snapshots of the girls being their beautiful selves!

Taeyeon shared on her Instagram on the 20th, "#TTS", along with stunning photos of the TaeTiSeo reunion.

SM Entertainment previously revealed that the girls are working hard for their upcoming comeback, which is expected to be sometime this fall, so it doesn't seem like fans have too long of a wait.

Also remember to tune into their new reality show OnStyle's 'THE TaeTiSeo' which is set to air on August 25 at 11PM KST!
