Diana's stylist says, "Back then you never flaunted your tummy when pregnant" telegraph.co.uk/fashion/royals…

The Duke and Duchess of Sussex announced they are expecting their second child on Sunday.

The news came on the 37th anniversary of the announcement that the Princess of Wales was expecting her second child, Prince Harry

While Meghan looked relaxed in a glamorously Californian way for the photograph celebrating the news, Diana was in the midst of a busy schedule of royal engagements when her pregnancy was confirmed

We look back at the outfits Princess Diana wore in 1984 while expecting Prince Harry

🔷 11 February 🔷

Days before Buckingham Palace confirmed that the Princess of Wales was expecting her second child, she embarked on her first solo tour, to Norway. Diana's bottle green velvet suit was created by Caroline Charles

🔷 15 February 🔷

The day after the Wales' happy news was announced, Diana visited the Jaguar car factory in Coventry. She covered any hint of a burgeoning bump with posies of flowers, choosing a coat by Catherine Walker and a netted hat by John Boyd

🔷 29 February 🔷

In Birmingham, the Princess once again turned to Catherine Walker for this scarlet and black velvet double-breasted coat. She carried her clutch bag close to her stomach - this drew focus to her pregnancy whilst also obscuring opportunity for a bump shot

🔷 March 2 🔷

Proving that being pregnant need not mean sacrificing experimenting, Diana opted for a menswear-inspired tuxedo and bow tie by Margaret Howell when she attended a Genesis concert

🔷 March 23 🔷

The Princess visited an orthopaedic hospital in Middlesex wearing a sumptuous velvet burgundy suit by Jaeger with a jaunty feathered hat by John Boyd

🔷 May 8 🔷

Diana made the statement pilgrim collar a cornerstone of her second maternity wardrobe as seen in this graphic printed blouse and skirt set which she wore several times while she was expecting Harry

🔷 May 14 🔷

By now, Diana's bump was unmistakable. This scoop-necked gown by Bellville Sassoon subtly emphasised her new shape with its empire line. The look was topped off with the dazzling Spencer family tiara, the heirloom Diana had worn on her wedding day three years before

🔷 May 20 🔷

For their next evening engagement, Charles and Diana attended a Luciano Pavarotti concert at the Royal Opera House. The Princess's beaded, tiered dress offered an elegantly classic solution to maternity eveningwear

🔷 May 24 🔷

Diana sported a relaxed look at the polo in Windsor, teaming a signature pair of sepia sunglasses with a striped cotton dress and mohair cardigan

🔷 May 30 🔷

Visiting Chester, Diana stuck to a nautical navy and white colour palette. The Princess wore a maternity coat created by Catherine Walker with a John Boyd hat

🔷 June 6 🔷

Diana turned to Catherine Walker once again for this drop-waisted gown which she wore to the premiere of Indiana Jones and the Temple of Doom

🔷 June 12 🔷

Charles and Diana were photographed at Kensington Palace with Prince William as the Princess neared her third trimester of pregnancy. She exhibited her love of collars once again with this sailor-style fuchsia dress

🔷 June 20 🔷

In the '80s, maternity clothes were generally made to conceal rather than reveal. This peach Jan Van Velden suit, worn at Royal Ascot, is an excellent example of that approach. Diana finished the look with a hat by Frederick Fox

🔷 June 27 🔷

Another new maternity outfit, another fabulous collar. Diana wore this Jan Van Velden suit a handful of times during her pregnancy. Here, she is seen visiting Odstock Hospital in Salisbury, finishing her look with a John Boyd hat

🔷 September 16 🔷

Prince Harry arrived on September 15. Leaving St Mary's Hospital, Diana looked businesslike in a Jan Van Helden coat and bow-tie shirt. The Duchess of Cambridge took inspiration from this outfit for a photocall to mark the birth of her second son, Prince Louis
