What do you think of this observation? Photos that sparked heated discussion about Princess Catherine’s appearance are below.

Catherine, the Princess of Wales, pleasantly surprised many by making her first public appearance since revealing her cancer diagnosis. She looked lovely as she joined her husband and children at the Trooping of Color, an important event marking King Charles’ official birthday.

Kate always dresses impeccably, and this time was no exception. She chose a white dress with black trim and ribbon detail on the neckline, which was a revamped version of an outfit she wore at an event at Buckingham Palace in May 2023.

The Princess added a white hat, pearl studs, and the Irish Guards Regimental Brooch to her outfit, showing her honorary position. She usually wears her brown hair in loose waves, but on Tuesday, it seemed longer, leading fans to speculate about the reason.

One person wrote that they are amazed by how long her hair has gotten. They are curious if she has been growing it out for the coronation. The idea of this makes them feel excited!

Indeed, Kate’s hair appeared longer than it has in recent years, retaining its thick and lustrous look.

Some people doubted Kate’s perfect hair because she is undergoing chemotherapy treatment.

One person online said it’s not her, and another person said it’s not Kate.

Another individual showed sincere interest, asking, “Do you want to find out how she manages to keep her hair during chemotherapy? This is a genuine question, not meant to criticize or anything like that.”

Some people online wondered about the medical side, questioning, “Is it possible to undergo chemotherapy without losing your hair?”

Others inquired if William was accompanying her and wondered how she still had her hair despite undergoing chemotherapy.

I always admire how quickly this elegant lady’s hair grew back after chemotherapy.

Politely asking, a user inquired if it’s possible that not all chemotherapy causes hair loss, wondering if the person’s hair loss could be due to wearing a wig instead.

Another comment was made, expressing disbelief about her illness.

Some people didn’t doubt anything about Kate, they just praised her for choosing to be by the King’s side on that important day. “Even while undergoing chemotherapy, she still looks beautiful!” a person commented.

Shortly before her first public appearance in six months, Kate opened up of her condition in a genuine post she shared on Instagram.

Standing next to a grand tree, representing strength during her treatment, Kate expressed, “I am amazed by the many kind messages of support and motivation.”

She talked about her chemo treatments, mentioning how on tough days she feels weak and tired, needing to rest. However, on better days, she feels stronger and wants to take advantage of feeling well.

She finished her post by expressing gratitude to all those who have provided support and good wishes. “I am truly grateful for your ongoing understanding, and to all of you who have courageously shared your experiences with me.”

Another subject about Kate that was popular among internet users was the new picture of her on the front of Tatler magazine.

British-Zambian artist Hannah Uzor painted the portrait of Kate, which received mixed reviews as some people felt it didn’t capture the likeness of the Princess.

Someone questioned if it was a joke on an Instagram post of the magazine. Another person stated that the person in the portrait was not HRH The Princess of Wales. Some people thought the quality of the portrait was disrespectful.

Catherine’s portrait received criticism after Charles revealed his all-red portrait painted by Jonathan Yeo. The painting showed the King wearing the red uniform of the Welsh Guards.

Before the buzz and debate over the royal portraits, Charles gave Catherine a significant title.

He made her a Royal Companion of the Order of the Companions of Honour in April at St. George’s Chapel in Windsor Castle.

Catherine has become the inaugural royal family member to receive this prestigious recognition. Instituted by King George V in 1917, this esteemed accolade recognizes outstanding accomplishments in the fields of arts, science, medicine, or government.
