Mischa Barton never fails to look AH-MAY-ZING!
The actress slash model gave Abraham Lincoln a run for his money at the Epsom Derby in a glittery Philip Treacy top hat that shined all the way into next week.
Mischa paired her fancy head topper with a black Delada tail jacket, black trousers and a printed blouse.
What a perfectly chic outfit for a day at the races!
