On my travels to D.C. one thing surprised me... the number of women wearing dresses and skirts while sightseeing. Long ones and to the knee ones. Sundresses and t-shirts. Occasionally someone in heels but I think they were the ones working there. It's a different look; dresses and walking/tennis shoes. Everywhere were flip flops. Are they THAT comfortable? My feet, my poor feet, I only took my comfortable walking shoes but the muscles ON TOP of my feet hurt worse than the 2 blisters on the bottom.
