The cocktail dress takes things to the next level. Longer hemlines are ideal, but it might be all about the silk material or the feminine ruffle details on the sleeve. There's something special about this dress, be it the color or the open back. There's no denying that a cocktail affair is fancy, so don't be afraid to dress up and strap on your heels.
