Money Diary: 27-Year-Old In Real Estate On 53k

Welcome to Money Diaries, where we're tackling what might be the last taboo facing modern working women: money. We're asking a cross-section of women how they spend their hard-earned money during a seven-day period – and we're tracking every last penny.
This week we're with a 27-year-old living in east London with her boyfriend. She works in central London as an analyst in a real estate investment company. She enjoys seeing friends, tries to get regular exercise and loves going to new bars and restaurants. She also goes to the theatre fairly frequently. She is trying to save £5,000 this year which is a bit of a challenge as she also has quite a few holiday plans, as well as her boyfriend’s 30th birthday in November, when she is planning to take him to the Fat Duck. As a result she is trying to live off £75 a week for non-essentials (clothes, beauty, socialising, etc).
