Turquoise and Blue Angela Kelly 'Neon' Outfit

This Angela Kelly outfit features a rather striking contrasting combination of electric blue and bright turquoise, it's almost a 'neon' look for Her Majesty, and one that ensures she's highly visible during engagements. The hat is mainly electric blue, with turquoise piping and a blue and turquoise yarn trim as a decorative feature, whereas the coat is mainly turquoise, with the collar, flap pockets and piping down the centre front being electric blue. The coat buttons have a geometric, somewhat Mondrian-esque motif.

The Queen debuted this look on a visit to Manchester on 14 November 2013, accessorizing it with the Jardine Star brooch (more photos and a video on the Manchester Evening News page here):

 

Then, the following year, on 29 April 2014, Her Majesty wore this ensamble again on a visit to Cotts Farm Equine Hospital in Narbeth, Wales (Daily Mail article can be found here). This time the coat was jazzed up with the Pearl Trefoil brooch:

 

It was another equestrian engagement for this look when the Queen selected it again on 18 October 2014 for the British Champion's Day at the Ascot racecourse. For this occasion, Her Majesty opted for a not-often-seen brooch in the shape of a floral bouquet made up of multi-coloured stones:

The next time we saw the Queen wear this outfit was on 11 January 2015, for Sunday Church at St Mary Magdalene on the Sandringham Estate (Daily Mail article here). The Queen Mother's Palm Leaf brooch was used:

 

 

Her Majesty repeated the look a couple of months later, on 26 March 2015, for a visit to the National Memorial to the Few in Capel-le-Ferne, Kent (Daily Mail article here), followed by a visit to Canterbury Cathedral, where stautes of the Queen and the Duke of Edinburgh by Norfolk artist Nina Bilbey, commissioned to mark the Diamond Jubilee, where unveiled (Daily Mail article here). The Queen wore one of Queen Victoria's Diamond Bow brooches:

The coat and dress then made a solo appearance at a traditionally hatless occasion, the Chelsea Flower Show, at a preview on 18 May 2015. As has become customary in recent years, the Queen wore a brooch in the shape of an Iris Unguicularis, the floral symbol of the Chelsea Flower Show, a present from the Royal Horticultural Society on the occasion of the Diamond Jubilee. Prince Harry accompanied the Queen on a tour of the garden designed for his charity, Sentebale (Hello! magazine article here):

Most notably, the Queen chose this outfit for her historic appearance on 9 September 2015, the day when she became the longest reigning monarch in British history, taking over from her great-great-grandmother Queen Victoria (Daily Mail article here). The Queen was greeted by cheering crowds as she boarded a steam train at Waverely Station in Edinburgh, en route the village of Tweedbank, where she opened the new £294million Scottish Borders Railway. Appropriately, she wore one of Queen Victoria's diamond bow brooches:
