I visited London for a weekend, and stayed with a friend in his lovely apartment. Soon as we got in, we hit the tube and went to the tourist attractions. Luckily for anyone visiting London, the West Minster stop from High Street, Kensington leaves you near a few big London sights. We jumped off the Underground on West Minster and immediately walked out to The London Eye & Big Ben, a few blocks away the Horse Guards.
My outfit for sight seeing in London was this cool militant green over lay, I wore it over a cropped tank and shorts.
