Pale Blue Bouclé Outfit with Navy Buttons and Navy Roses Trim

On 26 November 2015, the Queen debuted a new outfit for her arrival in Malta, where she was due to open the Commonwealth Heads of Government Meeting (Daily Mail article here).
The ensamble is comprised of a pale blue bouclé coat and hat; the most striking feature about the coat are its slightly oversized navy blue buttons, grouped in a row of three close to the neckline. The colour is echoed in the navy silk roses that embellish the hat, a creation by Angela Kelly. The Queen accessorized with Queen Victoria's wedding gift sapphire and diamond brooch:

The look was repeated on 16 March 2017, when the Queen officially reopened the National Army Museum in London following a 3-year redevelopment (Daily Mail article here). This time she wore the Queen Mother's Palm Leaf brooch to complement the outfit:

Pink Bouclé Outfit with Lace Inserts and Silk Peony Trim

The Queen debuted this pale dusty pink outfit for the renaming of the Marché aux Fleurs in Paris in her honour as Marché aux Fleurs - Reine Elisabeth II, on 7 June 2014, the last day of her State visit to France to commemorate the 70th anniversary of the D-Day landings (Daily Mail article here). The outfit is comprised of a dress and collarless jacket in a pale dusty pink, gold-speckled bouclé fabric with white lace bands inserted across the waist and cuffs.
The hat is an Angela Kelly creation, in white straw trimmed with a large band of the same bouclé fabric and a pink silk peony on one side. For the occasion, the Queen finished off her look with the appropriately floral Irish Blossom diamond brooch:

On 5 March 2015, the Queen recycled the suit to bid farewell to the President of the United Mexican States, Señor Enrique Peña Nieto, and Señora Angélica Rivera de Peña at the end of their State Visit to the United Kingdom. The Cullinan VI & VII brooches were worn:

The whole look was repeated on 15 August 2015, to attend a service at St Martin-in-the-Fields Church in London to commemorate the 70th anniversary of the end of hostilities with Japan in WWII, or VJ70 (Daily Mail article here). This time the Queen accessorized with the Cullinan V brooch:

On 4 May 2016, the Queen wore the dress on its own, again with the Cullinan V brooch, to receive Baroness Scotland at Buckingham Palace, on her appointment as Commonwealth Secretary General. Note that the dress features the same lace inlays at the cuffs and waist as the jacket:

On 5 April 2017, the Queen wore the dress and jacket to a ceremony at Windsor Castle during which she presented the Royal Lancers with a Guidon, or heraldic banner. Predictably, the Royal Lancers badge was worn as a brooch. After the presentation the Queen, the Regiment's Colonel-in-Chief, granted The Royal Lancers with the honorific suffix 'Queen Elizabeths Own' in recognition of their service to Her Majesty and to Queen Elizabeth the Queen Mother (Daily Mail article here):

Ice Blue and Turquoise Bouclé Outfit with Feathered Rachel Trevor Morgan Hat

This outfit is comprised of a collarless coat with turquoise fabric-covered buttons and a dress, both in the same pale ice blue-grey bouclé fabric with mini turquoise polka dots, plus a turquoise straw hat by Rachel Trevor Morgan, with a sharply upturned brim trimmed with a band of the same fabric as the coat and dress and a feather spray trim.

It was first worn by the Queen during her historic visit to the Republic of Ireland, the first from a British monarch in 100 years, on 18 May 2011. Her Majesty toured Government buildings and visited the Guinness storehouse. She wore her Boucheron aquamarine and diamond clips:

On 3 September 2011, the Queen repeated this look for her traditional appearance at the Braemar Highland Gathering in Scotland. As usual, Her Majesty wore her yellow gold Braemar Feather brooch:

 

 

The Queen then repeated this look on a very significant day, the 60th anniversary of her accession to the throne, for a visit to Dersingham School in King's Lynn, Norfolk, on 6 February 2012. For the occasion, a favourite brooch of the Queen Mother's, the Courtauld-Thomson Scallop Shell, was used:

 

 

The outfit then made another appearance in the year of the Diamond Jubilee, when the Queen wore it for that year's Maundy Thursday service at York Minster, which she attended accompanied by the Duke of Edinburgh and Princess Beatrice, on 5 April 2012 (Daily Mail article here). Her Majesty completed her look with the Jardine Star brooch:

 

 

The outfit, accessorised with a warm black fur scarf and the Nyzam of Hyderabad Rose brooch, was worn again on 10 February 2013 for Sunday church at Sandringham (Daily Mail article here):

 

Barely a fortnight later, on 21 February 2013, the Queen wore the dress on its own, paired with her pearl triangle brooch, for audiences at Buckingham Palace (Daily Mail article here, in the second photograph the turquoise polka dot detail that identifies this piece is more clearly visible):

 

And again on 28 February 2014, the dress, paired with the Cambridge Pearl Pendant brooch, was worn for a private audience at Buckingham Palace with German Chancellor Angela Merkel (Daily Mail article here):

 

 

The Queen chose again the coat and dress, albeit without the hat, ditched in favour of a floral silk scarf, for the train journey from central London to King's Lynn at the start of her traditional Christmas break in Norfolk on 18 December 2014, accessorizing with the not-often-seen Flame Lily brooch (Daily Mail article here):

  

 

This outfit was then recycled on 29 May 2015 during a visit to Lancaster, which the Queen undertook in her capacity as Duke of Lancaster (Daily Mail article here). The Duchy of Lancaster badge was worn:
