I just bought a dress just like this on to wear to holiday parties. I'm loving the dark blue color.

Silk Lark & Wolff by Steven Alan party dress cut long with a dropwaist trimmed with pleats. Cut low along the neckline with a folded collar detail. Buttoned at the back.♥

its a little casual for new years eve but its shiny and really, really cute. if your party is a on the chill side this is a really nice pick.
