The Duchess of Cambridge undertook a series of maternal mental health engagements today. She first visited The Maurice Wohl Clinical Neuroscience Institute at the Institute of Psychiatry, Psychology & Neuroscience (IoPPN) at King's College London. It is one of Europe's largest centres for neuroscience excellence.

Next, Kate toured the Mother and Baby Unit at the Bethlem Royal Hospital, part of NHS Maudsley Foundation Trust. The unit specialises in the treatment of antenatal and postnatal mental health illnesses including postnatal depression and post- partum psychosis.

Following from yesterday's all-blue ensemble for a visit to the Roe Green Junior School, Kate was back in her favorite hue for today's outing.

She teamed her blue mist Seraphine 'Natasha' Coat (£195) with the maternity brand's 'Florrie' dress (£65). She first wore this combination in January 2015 when pregnant with Princess Charlotte for a series of engagements in Kensington.

The Duchess complemented the Seraphine pieces with her navy Jaeger quilted clutch and Jimmy Choo 'Georgia' pumps in a matching navy suede.

Kate finished the look with her Sapphire & Diamond Oval Drop Earrings and Cartier Ballon Bleu Watch.

The Duchess of Cambridge visited the Roe Green Junior School in Brent today to launch a new Mentally Healthy Schools website. Funded by the Royal Foundation as part of the Heads Together campaign, the online resource will be available to every primary school in the UK and will give teachers and staff the clarity and practical resources they need to support pupils.

Kate stepped out in an all blue ensemble. She arrived at the school wearing her petrol blue Sportmax 'Gerbera' coat first worn for a visit to the Emma Bridgewater pottery factorywhen she was pregnant with Princess Charlotte.

She accessorized with a new Beulah London scarf (thanks to @Giulia_lelepug for the ID). It is the brand's 'Elena' scarf in Navy Henri Print (£79.17)

The Duchess also debuted a blue dress by Seraphine. The style is the brand's Royal Blue Tailored Maternity Dress (£99) from their LUXE collection - thanks to @evangelina_th for the ID.  The dress is designed to accentuate the empire waist with stylish gold button detailing under the bust. Cut for an elegant A-line shape, this knee-length dress is made in premium stretch woven fabric, and finished with 3/4 bell sleeves.

On her feet were the Rupert Sanderson 'Malory' Navy Suede Pumps.

Kate carried her navy suede Stuart Weitzman 'Muse' clutch.

She finished the look with her G. Collins & Sons Tanzanite Pendant Necklace & Earrings and Cartier Ballon Bleu Watch.

Following Kate's official event at Great Ormond Street Hospital this morning, her afternoon outing had a more casual tone.  The Duchess of Cambridge visited Bond Primary School - one of the 65 local schools that benefit from the  Wimbledon Junior Tennis Initiative offering free tennis coaching.

You may recall what an avid tennis fan Kate is; she is the patron of the Lawn Tennis Association (LTA) and has carried out multiple engagements involving junior participation in tennis, and Wimbledon in general.

Kate sported a familiar look for today's tennis workshop - a déjà vu repeat of the one she wore last October for an event with the LTA.

Today, Kate swapped her black PlayBrave 'Clarice' jacket for a white one (£129.00).

The outfit also consisted of her Monreal London Side Panel Track Pants (sold out). She first wore the $325 track pants in February 2016 for a tennis workshop with Judy Murray. 

On her feet were the Nike Air VaporMax Flyknit sneakers (US$190).

Kate rounded off her casual style with the Annoushka Pearl and Kiki Diamond Hoop Earrings worn earlier today.

The Duchess of Cambridge visited the Great Ormond Street Hospital today where she was on hand to open the new Mittal Children’s Medical Centre.

Kate brighten up the hospital wards in her new vibrant red coat by Boden.

 It is the 'Lena' style in the 'Red Pop' colourway from the British clothing retailer.

Crafted with pure cotton, this structured coat falls to just below the knees and is embellished with ruffles at the collar, the two front pocket and the cuffs of the long sleeves. Fully lined for comfort, it is completed with a button down placket with large statement buttons.  The coat retails for £220 and is currently in stock at Boden and John Lewis. If you are placing your first order with Boden (USA), you can get 20% off Kate's coat with promocode 4C6L.

The peach hued dress under the coat is believed to be the same one she wore with her Tara Jarmon coat in April 2013 when pregnant with George. The coordinating dress is said to be by “an independent dressmaker”.

Kate contrasted the bold hue with muted brown suede accessories. She carried her chocolate Emmy 'Natasha' clutch and on her feet were brown pointed-toe pumps, believed to be the same pair she first wore in Anglesey back in February 2016.

The Duchess has accessorized with her beloved Annoushka Pearl and Kiki Diamond Hoop Earrings.

Up next, the Duchess will visit Bond Primary School in Mitcham in her role as Patron of Wimbledon, to see the work of the Wimbledon Junior Tennis Initiative. It's past midnight in my part of the world so I'll cover this event tomorrow.

The Duke and Duchess of Cambridge spent the day in Coventry for a series of engagements starting with a visit to the Coventry Cathedral, followed by a stop at Coventry University and then a meeting with The Positive Youth Foundation.

The Duchess sported a familiar look, opting for an outfit she first wore in New York at the September 11 Memorial & Museum in December 2014 while pregnant with Princess Charlotte.  We saw the ensemble again a few moths later just before she went on maternity leave.
