Kate Moss got the business out of the way before going out last night, as she left the Arcadia offices in London (where Topshop is based) looking chic in her all black outfit. After her meeting she changed into another all black outfit and then headed to her friend Sadie Frost's first performance in her one woman show Touched For The Very First Time. Sadie had to learn over 90 pages of dialogue for the play, which is currently on at the Trafalgar Studios in the city. After the opening night was over, Kate took Sadie to a private members' club in Soho to celebrate! It seems like she's a good friend!
