Susannah Caroline Constantine[1] (born 3 June 1962)[2] is an English former TV fashion journalist, writer, style advisor, television presenter, author and clothes designer.

Constantine has been involved in fashion for a long period, originally working in America for Giorgio Armani and then John Galliano in London.

[3] Constantine and Woodall have designed their own clothing range for Littlewoods which made its debut in 2007, followed by the release of their latest fashion advice book, The Body Shape Bible.

[5][6] Through her paternal grandmother, Marie Leonie Francoise (née van Haaren), she is descended from Dutch prince William the Silent.

[9] Constantine originally did a year of Montessori training after she had left school but she then moved onto other projects[7] such as studying sculpture in Brussels.

[7][12] She wrote a book about present giving, which prompted The Daily Telegraph to write an article implying she had never done a day's work in her life, something which deeply upset her.

[11] She later came back to London working for designers Richard James, Patrick Cox,[10] Alistair Blair and John Galliano which gained her an understanding of fashion.

[11] She then started working with the British Brain and Spine Foundation and consequently met the sports editor of The Daily Telegraph.

[11] Whilst doing a piece for GMTV, he asked Constantine to report the women's World Cup Final in cricket.

[7] Constantine and Woodall became the co-founders of Ready2shop.com, but the business venture failed, and investors lost a reputed £10 million.

It ensured that they had further exposure in television and gained attention from Jane Root, controller of BBC Two, who signed them up after their book venture and their internet business had failed badly.

[12] Constantine began co-hosting What Not to Wear with Trinny Woodall in 2001, in which they criticised participants' appearances and fashion style.

Constantine and Woodall hosted What Not to Wear until 2005 and became renowned for their behaviour with the participants, direct advice,[16] and frequently referring to breasts as tits.

[17] A notorious moment arose when Constantine spontaneously pulled a female candidate's underwear down during filming as her knicker line was visible.

"[7] During her time co-hosting What Not to Wear, she and Woodall won a Royal Television Society Award in 2002 for being the best factual presenters.

[20] After Clarkson appeared on the show, Nasir Khan stated "I'd rather eat my own hair than shop with these two [Constantine and Woodall] again".

[21] On the show Big Impression, impressionist Ronni Ancona took to spoofing Constantine's presenting techniques on What Not to Wear.

[14][22] For charity, in 2002 during the BBC's Children in Need programme, both Constantine and Woodall performed their own version of Madonna's hit single "Vogue".

"[30] In 2006, Constantine and Woodall moved from the BBC to ITV to start a new show, Trinny & Susannah Undress..., on 3 October.

[49] When the campaign began, Littlewoods' sales rose by 18 per cent, with brand awareness and customers visiting the website rising as well.

[51] Constantine has co-written several style advice books with her fashion partner Trinny Woodall, which have sold over an estimated 2½ million copies worldwide.

The first season featured interviews with eight high-profile guests: Michelle Visage, Tan France, Elizabeth Hurley, Nile Rodgers, Trinny Woodall, Joe Sugg, Kristin Scott Thomas and Stacey Dooley.

[18] Constantine became a fixture in 1980s British gossip columns and newspapers as the result of her relationship with Princess Margaret's son, David Armstrong-Jones, Viscount Linley, which lasted for eight years.

[15] Constantine admitted that her relationship with Linley undeniably opened doors for her, but after they broke up, she was keen to put the episode behind her and become well known in her own right.

[62][63] Constantine married Danish entrepreneur and businessman Sten Bertelsen, who launched Death cigarettes,[13] with whom she has three children; Joe, Esme and CeCe.

[7] Constantine has spoken of the constant pressure to look good in public but affirms "We're as much in the business of dressing ourselves – but more importantly helping other women to do that.

The thieves broke into the villa on the French Riviera where they were staying, rendered Constantine and Woodall unconscious with chloroform, and then stole money and jewellery.

[65] In August 2014, Constantine was one of 200 public figures who were signatories to a letter to The Guardian opposing Scottish independence in the run-up to September's referendum on that issue.
