So Sleek, So Chic Dress, by ModCloth.
A (unintentional) Nightwing-inspired peplum cocktail dress? Get out of my dreams get into my Nightbird.
Unfortunately, this dress is no longer available on ModCloth*. However, this serves as a great example of how to rework a stellar costume design into a chic, ready-to-wear ensemble.
*BRB crying forever~
I would wear this dress, and it would look amazing on my curves. YUP.
