Kate was in a mix of old and new pieces for a joint engagement with William today.
The Duke and Duchess were at a Coach Core event in Essex.
More from USA Today:
Prince William and Duchess Kate got playful during a visit to Coach Core Essex at the Basildon Sporting Village outside London Tuesday.
Coach Core program helps to engage a diverse local community with sports – and the royal couple seemed to have fun taking part in the athletics and getting friendly with the students.
The Duke and Duchess speaking with coaches and graduates from the program as well as new program apprentices.
Coach Core’s goal is to “harness the power of sport & its ability to change lives and empower young people.” Since it began in 2012, 99% of graduates enter full-time education or secure employment. Coach Core targets communities which have the highest levels of youth unemployment and social deprivation.
This morning Coach Core noted that “…we have a wide variety of partners in Essex, including inclusion programmes like Sport for Confidence, which The Duke and Duchess of Cambridge will get to see first-hand as they participate in a game of boccia with our apprentices later today.”
Below, Kate playing boccia. She kept getting the giggles.
Her team was taking on William’s team. (Coach Core says the way to find out which team one is via its Instagram Stories.)

Sport for Confidence summed up the day this way:
A groundbreaking day, never seen a room full of so many smiles.
Barriers broken.
When it was time to leave Sophia Mitchell had a pretty posey for the Duchess.
Now for our look at what Kate wore, starting with her Smythe 2-Button Blazer ($795, now sold out). It is a wool/linen/nylon blend in a classic Prince of Wales check, also known as Glen Plaid in some quarters.
The piece is described as having a “…traditional riding blazer feel, featuring a contrast collar, flattering pocket flaps and oversized leather buttons.” More on the fabric pattern from GQ:
The term glen plaid is derived from the Glenurquhart valley in Scotland, where the textile was first employed way back in the 19th century. Glen plaid is often dubbed Prince of Wales check, after the ever-rakish Prince of Wales Sir Edward VIII who favored the fabric for his bespoke suits.
Valerie suggested Kate’s turtleneck might be this & Other Stories piece ($69).
It is 100% merino wool with a snug fit and no embellishment, nor is there ribbing at the collar or cuffs. I tried lightening photos to get a good look at Kate’s sweater but just couldn’t see enough detail to tell if this was the top Kate wore today. Kate’s skinny jeans are not yet identified.
Kate wore her Fallon Dry boots (£295, about $375 at today’s exchange rates) from Russell and Bromley. The boots are an Aquatalia design made for Russell and Bromley in weather-resistant black suede with a 2.5″ heel. 
The Duchess had on her White Topaz Cushion Drop Earrings by Kiki McDonough.
And she wore her Cartier Ballon Bleu watch. (We show it as worn on another occasion.)

I think Kate looks amazing! I am in. My 50s, and I absolutely do not have a lovely figure like Kate’s, but I only wear skinny jeans. I think they flatter any figure.

For those unfamiliar with riding jackets, I want to give a little information about how a riding jacket traditionally fits and how it traditionally looks like in case you are wondering how this is jacket is inspired by equitation wear as I myself am an equestrian (I do English Equitation, Para-dressage and I'm learning Showjumping.) The particular model of riding jacket this appears to have been styled after is a showjumping or hunt jacket as there are no tails as I like to call them; you can easily bring a showjumping jacket into your modern day wardrobe.
Jackets traditionally have a 3-4 single button closure (with same amount of decorative buttons on the sleeves) and are traditionally made of wool, although newer technologies have allowed them to be made of nylons and other synthetics that look just as polished but are waterproof and keep a rider cool. Along with a notched collar, a single vent is traditional, but double vents help keep the jacket flat against the saddle. Traditional colors are navy, black and hunter green.
Jackets should be fitted enough that the form of the rider is seen, yet not so fitted that the arms and shoulders cannot move freely in any direction. Often, you see coats fitted with about 1/8" - 1/4" (some insist on 1/2") of room to breathe so riders can move our bodies effectively; the shoulder seam always sits on the shoulder hinge or riders can't move their arms. Hunt and jumping coats are cut two to three fingers lengths above the thigh so riders have freedom to sit up in the saddle.
Keeping this in mind, you can see much of the equestrian flare this jacket has. It has the unusual rider cut, the 4 button decorative sleeve buttons, and the new trend in equine sports - the top part of the collar being one color and the bottom being the same color as the jacket. (In fact, Tredstep makes a jacket where you can switch out the top portion of the collar for another color. It's the big thing right now.) You can also see the equestrian sensibility in the fact she wears a turtleneck and skinny jeans. All she needs is riding boots and a helmet!
I really loved this post because I am disabled myself and do sports. It's so important to get us involved in the community and see us as valuable people, yet so many write us off as invalids and not worthy of receiving updates to the community or getting involved.

Hi! I was wondering if anyone knows when she wore these earrings on other occasions. I don’t remember seeing them before. Thanks!
