Why Princess Diana stopped wearing frills

It was the era of perms, power suits and polka dots, so it's no wonder some of the biggest trends to emerge from the 1980s look flattering with hindsight.

And it has now been revealed why one of the decade's biggest fashion figureheads, Princess Diana, eventually turned her back on puffy sleeves and oversized ruffles in favour of a more slimline silhouette.

Eleri Lynn, the curator behind a new exhibition on the late Princess of Wales' wardrobe, believes the royal ultimately came to realise that they made her look bad in photographs, reports the Daily Mail.

Explaining why Diana, who was killed in a car crash in 1997, moved away from the New Romantic look, Ms Lynn said: "I think she realised the frills and the ruffles that she was so partial to didn't work particularly well in press photographs.

"It gave a cluttered overall appearance and we know that she did read her own reviews. So around that time you see a real change in her silhouette as it becomes much more sophisticated, much more sleek."

She added that the more subtle embellishments Diana later embraced "popped" when the camera flash turned on them.

Ms Lynn was discussing some of her most memorable ensembles on BBC's Woman's Hour on Thursday with fashion historian Amber Butchart.

The duo also looked at Diana's so-called "tuxedo dress" by Belleville Sasson, worn to a performance of the Marriage of Figaro in 1989.

Ms Lynn praised the "theatricality" in the princess" wardrobe and said: "When she had learned the unwritten rules of royal dressing, she started to break them.

"The Royal family traditionally wear black only in mourning but Diana particularly liked wearing black. It suited her very much, she was 5ft 10in and blonde and looked great in these colours."

She added: "[Diana] was the first female member of the Royal family to be pictured wearing trousers for example for evening events, which she often wore with jackets and ties - which is quite a bold look even today. And I think not something which is typically expected of a princess."

Amber agreed that it was an "interesting choice" for a princess, saying: "Historically, tuxedo wearing was seen as slightly subversive for women. This goes back to Hollywood in the 1930s, Marlene Dietrich wearing a tuxedo smouldering on screen in films like Morocco.

"There is a slight frisson to this mixture of masculine styling for womenswear, and so it does make it a very unusual and bold choice for a princess."
