Body language expert Judi James analysed the young royal’s appearance at the event.
The 17-year-old appeared confident and mature ahead of the event, having recently lost her beloved grandfather Prince Philip, who passed away at age 99.
In fact, the royal paid tribute to her late related by wearing his navy suit jacket.
Judi James said of the royal, who is currently 15th in line to the British throne: “Although she has clearly been mentored by her mother Sophie, Louise shows all the signs of acquiring a very unique style of charisma as she grows in confidence as a featured royal.”
She described Louise as having “this look of growing strength underpinned by a hint of defiance, as though determined to be successful and talented in her own right as well as falling into line as a member of the next generation of the royal Firm.”
However, the expert claimed the royal shows some shyness, still.
“The way she pulls the strap of her shoulder bag into the middle of her torso suggests here she’s still not totally comfortable with all the press attention and the way her father walks close to her, slightly protecting her by allowing one arm to fall in front of her body, reflects that but recently her look overall, with the slightly jutting lower jaw and the one brow raised, is one of increasing resilience and confidence,” Judi said.
Fans responded to Lady Louise’s appearance with praise.
Rosamund Pike played the iconic Amy Dunne in the film adaptation of Gone Girl.
She also played Elizabeth Bennett in the 2005 adaptation of Pride and Prejudice, alongside Keira Knightley.
Later Lady Louise appeared in her carriage driving dress, a green suit with a very smart hat.
“Oh how absolutely fantastic. She must have felt SO proud – and she looks a million dollars! Beautiful ponies,” one fan wrote.
