Reardon was born in New York to London architect Patrick Reardon. She attended Garden House School, Bute House Preparatory School for Girls, Cheltenham Ladies' College and Stowe School. Reardon rejected a place at the University of Exeter to begin a career in journalism.
Reardon began her career on the US edition of Vogue magazine as its youngest ever fashion assistant, and was made fashion director of the British Tatler magazine at the age of 21, also its youngest ever. Reardon remained in this position for 9 years, before gaining the attention of Vanity Fair editor Graydon Carter, who gave her the job of contributing editor in 1999, in which she spent eleven years in the role. Reardon has also contributed to most of the UK's national newspapers and written three columns in The Times, who named her one of Britain's best writers.
In 2007, Reardon launched her own website called TopTips.com, giving "real tips for real women", which later became a best-selling book (translated into Russian and Indonesian, among other languages) and spawned a column in the Daily Mail and a regular slot on GMTV. Also in 2007, Reardon was named one of London's 1,000 Most Influential People by the Evening Standard.
Reardon has previously dated Rupert Fairfax, Old Etonian aide to Prince Charles, actor Samuel West, former Spectator editor Matthew D'Ancona, and former executive M&S chairman Sir Stuart Rose. In the Summer of 2013 she married bloodstock agent Charles Gordon-Watson.
