Prince George and Princess Charlotte stole the show in the new official portrait with their great grandmother Queen Elizabeth II, which was released on the occasion of her 90th birthday Thursday. The British monarch posed in the picture with her five great-grandchildren and two youngest grandchildren. The kids were dressed by their stylish mom Kate Middleton, who left no stones unturned to treat royal fans to doses of cuteness.

In the new portrait, the 2-year-old George stands next to the queen, whom he calls his "Gan-Gan." The toddler is dressed in a Fair Isle style jumper and a Peter Pan collar white top.

George pairs his look in red shorts and his signature navy knee-high socks by Amaia, which he has in quite a few colors. The tot’s blue knitted wool-blend jumper is by Spanish brand Fina Ejerique from its Autumn/Winter 2015 collection. He sported the same brand in official portraits released by Kensington Palace during Christmas.

Little George paired his look with his trusted navy Start Rite Jo shoes and his Amaia Kids ribbed knee-socks. His blond locks were combed over to the side. “George looks so cute, he’s a beautiful boy. Our happiness is indescribable! To be chosen to be part of the historical portrait of HM Queen Elizabeth with her grandchildren and great-grandchildren is something we could not have imagined even in our dreams,” Ana Pérez Ejerique, creative director of the Spanish label, reportedly said.  

She added that the kids’ dresses show that the British royals trusted their brand and Spanish fashion. Ana said that George’s cardigan could have been bought in one of the shops in the U.K. that sells their brand. Besides, Amaia Arrieta of Amaia Kids reportedly said that the kids looked adorable and natural in the new portrait, adding that Elizabeth must be very proud to show off all her grandchildren.

Meanwhile, Charlotte wore a strikingly similar floral dress like the pink frock she wore in December for her first solo portraits released by Kensington Palace. It is a frock by baby and childrenswear Spanish designer m&h. The dress is from the label’s Autumn/Winter 2015 collection and is already sold out.

Charlotte’s frock featured a dainty floral print, a frilled collar and matching bloomer-style knickers, also from m&h. The little princess wore a beige knitted cardigan from the online Spanish childrenswear boutique Pepa & Co. The microfiber cardigan featured pearl-like buttons, and is currently on sale for just $27. 

It is believed that the kids’ Spanish nanny Maria Teresa Turrion Borrallo bought the dress in the city of Valladolid, in northwestern Spain. Charlotte paired her dress with Amaia tights and white Emma Pre-Walkers.  

Margarita Pato of m&h reportedly said their clothing is made by hand, using fabric from Spain. Charlotte’s dress is almost one-of-a-kind as only a few pieces of each item are made. However, there is some good news for parents of toddlers who want to replicate the royal baby’s style. Borja Echevarría of m&h reportedly said the item can be replicated for customers if they still have the same fabric.
