And now it's time for another A-lister to blow out the candles—we're looking at you, Sandra Bullock ! The Oscar-winner turns 50 today, and we're celebrating by taking a look back at some of her greatest fashion hits. If dressing for success is any indication, then it's no surprise that some of Sandy's best looks come from past Oscar's red carpets. Call it coincidence if you will, but we have a feeling the 2010 Best Actress winner may have dressed to match her shiny new prize with her gorgeous Marchesa gown at the 2010 Academy Awards.
