There are cultural differences between England and America in many respects. But that doesn't stop British socialites Annabelle Neilson and Caroline Stanbury from running in similar social circles with Americanexpats Juliet Angus, Caprice Bourret, Marissa Hermer and Noelle Reno, who all enjoy a posh London lifestyle in Ladies of London.
