Taeyeon released more teasers for her solo comeback.

The veteran idol star is coming back with a new solo album 'Four Seasons.' Contrast to the comfy casual look in the previous teasers, Taeyeon has taken on an elegant concept in a dress for the third set of teaser images and video. 

Meanwhile, the MV is scheduled to release on March 22 and the full album will drop 2 days later on the 24th.
