president Obama's First daughters

They've been hobnobbing with some of the world's most powerful people, flying country to country on Air Force One on their whistle-stop tour of Europe.

But Malia and Sasha Obama have been using their stop in Milan to relax and let their hair down - hitting the fashion capital's shops and visiting art galleries.

The First daughters made an early morning visit to the prestigious Fondazione Prada art gallery today, dressed in short sleeves in the city's searing summer temperatures.
