Kate's McQueen gown
One of our absolute favourite dresses on the Duchess! Didn't Kate look amazing in this exquisite blue Alexander McQueen gown at a state banquet at Buckingham Palace? The royal teamed the dazzling dress with Princess Diana's Collingwood pearl earrings, Queen Alexandra's wedding gift necklace and the beautiful Lovers Knot tiara.
Meghan's Royal Variety outfit
The pregnant Duchess wowed everyone in this stunning monochrome floral top by Safiyaa and black floor-length skirt at the Royal Variety Performance.
Princess Eugenie's bridal gown
We still can't stop staring at Eugenie's wedding dress! The royal was breath-taking in the Peter Pilotto gown, featuring a low cut back to reveal the Princess' scoliosis scar. Eugenie looked radiant on her special day with husband Jack Brooksbank.

Beatrice's elegant teal dress
Beatrice looked so chic in this teal Roksanda gown with a coordinating headband by Stephen Jones at her sister Eugenie's wedding. She also wore a pair of nude Gianvito Rossi nude heels – the same pair the Duchess of Cambridge wore when introducing Prince Louis to the world.

We couldn't leave out Princesses Beatrice and Eugenie's British Vogue debut! They both looked gorgeous in their fashion-forward outfits, don't you think?
Sarah's chic guest look
The mum of Princesses Eugenie and Beatrice wore this gorgeous navy and pink dress by Emma Louise Design to the wedding of Meghan and Harry in May. She looked fantastic!
Meghan's wedding dress
Here it is, Duchess Meghan's beautiful bridal gown by Clare Waight Keller for Givenchy. The simple yet classic dress surprised us all and the design is timeless.
Meghan evening bridal gown
Thanks Meghan for treating us to two amazing wedding dresses! The Duchess' evening gown was a sleek halter neck number designed for her by Stella McCartney.
The Queen's best look
We think the Queen is simply stunning in this vibrant outfit. Just love that bright light turquoise shade, the pink flowers in her hat and her matching pink lippy. The monarch wore the ensemble to a visit to Berkshire in October.
Duchess Kate in yellow
Has Kate ever looked better? Sunny yellow is so her colour and she looks fabulous in this figure-hugging dress by Dolce and Gabbana at Wimbledon.
The Duchess does tartan
Another style win for Kate. The mum-of-three stepped out in the Emilia Wickstead midi skirt in December looking so festive. Love it.
Camilla's angelic dress
The Duchess of Cornwall was a vision in this beautiful floor-length white dress with pretty silver embellishment on the top layer. She wore it to an official dinner in Athens in May.

Sophie's metallic skirt
Just wow. The Countess of Wessex hit high style notes during her trip to Paris when she stepped out in this gorgeous metallic pleated skirt by Emilia Wickstead.
Letizia's daring dress
We loved this plunging midnight blue cocktail dress by the stunning Queen Letizia of Spain. The monarch wore it to 40th anniversary of the Spanish Constitution in Madrid and got tongues wagging online with the racy lace detail.
Polka dots for Letizia
Such a fun dress and one we'd love in our own wardrobes. Queen Letizia wore the cute monochrome polka dot number on a royal outing in Spain in September.
This floral Erdem gown is another of our favourites on Kate this year. She wore it for the first evening engagement of she and Prince William's royal tour of Sweden and Norway in January.
She stunned in Erdem (once again!) for a visit to the Victoria & Albert Museum in October. The embellished bouclé-tweed midi dress, £1,395, fit her like a glove. She teamed it with her Jimmy Choo Romy heels in Bordeaux velvet.
Lady Kitty's wow dress
Lady Kitty Spencer, the niece of the late Princess Diana, wore this gorgeous black and jewelled dress to the premiere of A Star Is Born in London in September. Such a glam gown.
Charlene's chic braces
A unique look for a royal and one we LOVED. Princess Charlene of Monaco was such a trend setter in this cool trouser suit, crisp white shirt and retro braces at the Princess Grace Gala Awards in New York.

Meghan wowed everyone in her first ever royal gown during her royal visit to Fiji in October, teaming it with a pair of show-stopping diamond earrings.
Mary's cape dress
Such a sophisticated look! Crown Princess Mary of Denmark looked sensational in this navy cape dress for a school visit in Copenhagen.
Maxima oozes glamour in orange
Queen Maxima of the Netherlands looked sensational in this burnt orange one-shouldered gown with stud detailing on a visit to Cape Verde. One of her best outfits!
Rania's 50s look
We stepped back in time with the beautiful Queen Rania of Jordan in April when she showcased this elegant outfit. What a cute skirt and blouse combo and we love those heels.
Rania nails athleisure
We're so into this look! Rania channels her inner Cheryl as she works her casual-chic trousers and sporty top – with heels. Amazing.
