Vanessa Paradis, Vanessa Paradis Oscars dress

Mrs Johnny Depp is usually the epitome of French chic, but this black Chanel crêpe silk creation screams faux pas. Add bright red lips and nails, pale foundation and a gothic white gold and diamond necklace and poor Vanessa looks a bit like a schoolgirl going through a Goth stage. Sack that stylist. 

What kills it: 
The dress makes her look as if she's got no shape. That combination of bright red lips, black outfit and porcelain skin is enough to make anyone look like Morticia Addams.
