White Outfit with Pewter Pixel Detail and Contrast Black Piping

The Queen debuted this look on 5 June 2014, during her visit to France to commemorate the 70th anniversary of the D-Day landings.
We first got a peek at the dress at St Pancras railway station in London, where the Queen marked the 20th anniversary of the opening of the Eurotunnel. The dress was worn underneath a white coat with navy bow trimming:

Upon arrival in Paris, the Queen emerged in a new short jacket and hat. The dress is minutely embroidered with pewter-coloured sequins that form a sort of pixelated motif, while the jacket is white silk/wool crepe trimmed with a large band of the same sequinned silk and contrasting black piping. The same trimmings are empoyed on the Angela Kelly white straw hat (Daily Mail article here). The Queen had swapped brooches as well, selecting the Botswana Sorghum brooch in favour of the sapphire and diamond grapes she had worn on departure:

 

The Queen repeated the outfit, minus the hat, on 4 July 2016, when hosting a reception at the Palace of Holyroodhouse in Edinburgh to recognize public service in Scotland (Daily Mail article here). This time she wore no brooch:

 

 

Pink Floral Silk Dress with White Jacket and Hat

The Queen debuted this look, comprised of a marshmallow-shaped, white piqué hat with floral silk braided piping by Angela Kelly, a short collarless jacket in the same piqué fabric with braid trim and floral embellished buttons and a pink and white floral print silk dress, on 29 October 2011 on the final day of her Australian tour at the Great Aussie BBQ in Perth (Daily Telegraph article here). It is a slightly unusual style for Her Majesty, who usually favours coats and only rarely wears jackets, but one that I think was perfect for an informal occasion like a BBQ! That time the Queen accessorized with the Flame Lily brooch:

 

 

 

The dress was repeated on its own for two official photographs taken by Mary McCartney and released on 8 September 2015 to mark the day the Queen became the longest reigning monarch in British history - overtaking Queen Victoria on 9 September (Daily Mail article here). The Queen wore her pink topaz and diamond brooch:

We finally got to see the complete outfit again on 9 June 2016, on the eve of her official 90th birthday celebrations (Daily Mail article here, the outfit is erroneously referred to as new). The Queen wore it, again with the pink topaz brooch, to launch the Commonwealth Hub, which brings Commonwealth organisations together, at Marlborough House in London:

Royal Blue Karl Ludwig Outfit and Angela Kelly Feather Trimmed Hat

Another look debuted at Royal Ascot, on 17 June 2015, this royal blue silk crêpe coat with floral silk dress is by couturier Karl-Ludwig Rehse. The matching hat, covered in royal blue crepe, with a white sinamay, trimmed with white flowers and blue feathers trimmed in the shape of fern leaves, is by Angela Kelly (Daily Mail article here).

For its first appearance on Day 2 of the meeting, the Queen accessorized with Queen Victoria's sapphire and diamond brooch, a wedding present from Prince Albert:

 

 

 

 

 

Sky Blue Karl Ludwig Coat and White Angela Kelly Hat

This sky blue Karl Ludwig outfit with floral trim and white straw Angela Kelly hat was first worn on 18 June 2010, Day 4 of the Royal Ascot races, accessorised with the Boucheron aquamarine and diamond clips:

 

 

It was repeated very soon afterwards, on 22 July 2010, for a garden party at Buckingham Palace, accessorised with the Queen Mother's Palm Leaf brooch:

 

 

On 20 May 2014, the Queen visited HMS Lancaster at Portsmouth Naval Base. The visit provided some fantastic photo opportunities! The Queen is pictured wearing the largest of Queen Victoria's Bow brooches:
