Mischa Barton attended the New York Times Style Magazine Party in Milan, Italy dressed in this on-trend number by Karta. The dress is adorned with geometric appliqués with off-white stones. You can purchase the dress on Neiman Marcus's site here. It costs around KD 110.
The dress can be worn during summer and winter, simply add opaque stocking, stacked heel and cover yourself with a trench coat or a cardigan. Good Luck!
