Tahari Peacock Blue dress size 14

Elegant dress w neckline ruching detail. Color is a deep teal, think a Peacock blue (pics make it look more blue than it is.) back zip, a little wear at belt line. Also, this came w a belt but I can't figure out which one. Happy to add a belt but it may not be correct! Bonus points if you can find a pic of the dress online! it's probably from around 2012.
