British singer and actress, Samantha Barks played Eponine in Les Miserables! I actually loved her character and tonight, she hit the red carpet at the Oscars in this fabulous Valentino (from Spring 2013) stunner which has a plunging neckline and back. Many debated on whether this was a no no but I think it was edgy enough to raise and eye and yet in the lines enough where it was appropriate to wear to an event such as this. With such a chic dress, she completed the look with this fabulous diamond sunburst necklace.
I love that necklace! She looked flawless!
