Oscar de la Renta always makes the most sensational frocks. I've been watching the third series of the Rachel Zoe Project this last week and it included the episode where Rachel is dressing celebrities for the 2010 Oscars. She chooses this amazing Oscar de la Renta dress for Cameron Diaz and she looks stunning.
Not quite in the same league but eminently more wearable is this gorgeous Oscar cocktail frock from Net-a-Porter. At 3100 pounds, it's a little out of the price range at the moment but I'll be on the look out for a similar dress with a black guipure lace overlay once summer comes around and the baby is wearing it's own fashion statements.
The fifties silhouette is so flattering and the scoop neck tends to suit me well. I'd see Carey Mulligan in something like this for sure. I have so many pearl necklaces to wear with a dress like this. Completely trans-seasonal, you could wear it with a fitted blazer in winter or a pair of sandals in summer. Princess Mary could totally rock this look. It's a classic style that is ageless - so very classic Oscar.
