Turquoise Coat and Rachel Trevor Morgan Hat with Red Rose

A turquoise wool 3-button coat in a classic cut, with turned-up cuffs, complete with a Rachel Trevor Morgan straw hat with a large turquoise velvet sash trimmed with an oversized red silk rose and wispy red and turquoise feathers. The matching silk dress has a floral pattern in magenta and green on a turquoise background.

The Queen debuted this look on 19 October 2006, when she chose it for her arrival in Tallinn, Estonia, during a visit to the Baltic Republics. The Australian Hibiscus brooch was selected (this is a look that allows great versatility in stone colours, thanks to the turquoise/red combo):

With Estonian President Toomas Hendrik Ilves:

Then it was worn again on 22 June 2007, Day 4 of the Ascot races, paired with one of Queen Victoria's Bow brooches:

 

Then it was repeated the following year, on 5 June 2008, for a series of engagements in Cumbria. The Cullinan V brooch completed the look:

 

 

Then, on 6 May 2009, the Queen stood out in her turquoise outfit among the red coats of the Irish Guards, when she presented new colours to the 1st Battalion Irish Guards at Windsor Castle. For this occasion, the badge of the Irish Guards was selected as a brooch:

 

 

Later that same day, the Queen, accompanied by the Duke of Edinburgh, travelled to Northern Ireland for a 3-day visit; for this second engagement, she wore the Nizam of Hyderabad Rose brooch:

 

The Queen repeated this look once again later that year, on 13 June 2009, when she wore it for Trooping the Colour, paired, as usual, with the Guards' badge:

 

 

A year later, on 20 May 2010, the Queen repeated the ensamble for a day of engagements in Yorkshire:

 

The following month, on 14 June 2010, the Queen made an appearance at the Guards' Polo Club in Windsor for the Queen's Cup match, accessorising her coat with the Flower Basket brooch

Interestingly, the Queen drove herself to the event (and...shock, horror! She didn't wear her seat belt!):

 

 

The Queen recylced the look again on 14 July 2010 to attend a livestock show at Castle Douglas, in Galloway, Scotland. The Jardine Star brooch was worn:

 

 

On 17 July 2012, we got a proper view of the dress that goes with this coat, when the Queen wore it for an audience at Buckingham Palace with Mrs Aloun Ndombet-Assamba, the High Commissioner for Jamaica. It looks as though the Pearl Trefoil brooch was used:

 

 

 

Ruby Red Wool Coat and Rachel Trevor Morgan Hat

This ruby red wool coat and dress combo with felt Rachel Trevor Morgan hat, trimmed with a felt flower and curling ribbon on the side, has been worn by the Queen quite a number of times. Its first appearance was on 20 March 2008, when Her Majesty attended the Maundy Thursday service at the Anglican Cathedral in Armagh, Northern Ireland. It was accessorised with a ruby and diamond brooch in the shape of a spray of flowers, that belonged to the Queen Mother:

Subsequently, on 23 October 2008, the Queen repeated it upon arrival in Bratislava, at the start of a State visit to Slovakia. Again, a brooch from the Queen Mother's collection was selected, the Australian Hibiscus brooch:

With Slovakian Presiden Ivan Gasparovic:

On the 18 January 2009, we saw again this outfit, and the Australian Hibiscus brooch, worn to church at Castle Rising in Norfolk, near Sandringham:

Then, the following month, on 20 February 2009, there was another repeat, when the Queen and the Duke of Edinburgh visited Thames Valley University to open a new building, Paragon House. A gold, diamond and ruby brooch in a modern, arched design was selected:

Months later, on 29 October 2009, the same outfit, down to the same brooch worn in February, was recycled for a visit to the Newmarket Animal Trust in Suffolk, during which a tree-planting ceremony took place:

It was then more than a year before this look was seen again in public, again paired with the Australian Hibiscus brooch, when, on 17 November 2010, the Queen visited the Advanced Manufacturing Research Centre at the University of Sheffield, donning a pair of 3D glasses:

The Queen was again in red on 31 March 2011, when she paid a visit to RAF Valley, a Royal Air Force station on the island of Anglesey, Wales,  where Prince William was stationed as a search and rescue helicopter pilot. Again, Australian Hibiscus brooch in use:

It was ever so slightly windy on the day:

Later that year, the Queen chose again this ensamble when she visited East Surrey College on 18 November 2011, accessorising with her Flower Basket brooch:

The following month, on 18 December 2011, the Queen paired this coat with a different red hat for a Sunday church service at Wolferton in Norfolk:

The coat was worn again, accessorised with one of Queen Victoria's Bow brooches but no hat, when the Queen left King Edward VII Hospital in London on 4 March 2013, after being admitted with symptoms of gastroenteritis:

On 29 January 2014, the Queen repeated the outfit when she opened the new village hall at Thornham in Norfolk, accessorising with a six-petal diamond flower brooch (and a dainty flower basket!):

We saw the outfit once again for a church appeareance when the Queen selected it on 4 January 2015 to attend the Sunday service at St Mary Magadalene on the Sandringham estate. No brooch visible, probably hidden beneath the large black fur collar. Incidentally, this appearance made front page news on British papers, as it came amid the sex scandal that embroiled the Duke of York in a US court:

After a nine-month hiatus, the outfit was worn again to the 200th edition of the Braemar Highland Gathering, a fixture in HM's Scottish engagements calendar, on 5 September 2015 (Daily Mail article here). Unsurprisingly, the yellow gold Braemar feather brooch was used:

I strongly suspect the Queen was wearing the matching dress when she received the Prime Minister of New Zealand, John Key, at Windsor Castle for a private audience on 30 October 2015. My guess is based on the similar style of the buttons. HM was wearing the gold trellis brooch:

The outfit was repeated on 29 January 2017, when the Queen attended the Sunday morning church service at St Mary Magdalene Church on the Sandringham estate (Daily Mail article here). She wore her gold lacework brooch:

Angela Kelly Coat, Dress and Suit Combo

This Angela Kelly hat with feather details in deep crimson is designed to be worn with either a boucle coat with a shawl collar, a skirt suit in the same fabric with a collarless jacket and off-centre, self-covered buttons and a dress, thus allowing a great versatility. All the pieces have prominent seam detailing.

Below we see the coat option in use on 25 December 2009, for the Christmas Day service at St Mary Magdalene Church on the Sandringham Estate, accessorised with black patent boots and festive rubies in the shape of the Queen Mother's Floral clips:

 

On 26 October 2010, the Queen welcomed the Emir of Qatar and his wife at Windsor Castle, at the start of the couple's State visit to the UK. That was a great day fashion-wise, as we saw both the coat and dress in all their glory. Pinned to the Queen's coat was her gold lace-work brooch, set with diamonds and rubies, a wedding present from the Jewelers and Silversmiths of Great Britain. Very 1940s in style, a splendid piece in my opinion:

 

The Australian Hibiscus brooch, set with rubies and diamonds, made its appearance once inside, when the Queen took off her coat and revealed the dress underneath:

 

 

On 15 February 2012, the Queen attended a multi-faith reception in Lambeth Palace in London. This outfit was a great choice for the occasion, as it was in the same palette as the robes of many of the ecclesiastics in attendance, as shown below in the photo with the Archbishop of Canterbury Dr Rowan Williams. The Flower Basket brooch jazzed up the outfit:

The dress reappeared for audiences at Buckingham Palace on 19 November 2014, when the Queen received His Excellency Mr Tadej Rupel, the Ambassador from the Republic of Slovenia to the Court of St James's:
