Kate Middleton received some negative feedback after she refused to wear a black gown to the 2018 BAFTAs.

The Duchess of Cambridge graced the BAFTAs red carpet in a forest green Jenny Packham gown with a black tie. Middleton showed off her baby bump in her loose and flowing gown that is tight-fitting around the stomach.

Most of the female celebrities and personalities who attended the event opted to wear black to support the Times Up and #MeToo campaigns which support women's rights. As a result, many were disappointed that the royal mom did not join in and show her support for the causes, with some questioning her sincerity in helping women.

"[Very] disappointed that Kate Middleton didn't wear BLACK in solidarity with other women. I guess she wanted to look different to commoners, the proletariat that pay taxes to support her lifestyle! Shameful!" JohnR EU posted on Twitter.

"Kate Middleton shuns #timesup black dress code, clearly not a woman’s woman! #EEBAFTAs," Twitter user Johanna wrote.

However, some also came to Middleton's defense by stating that the royal family does not get involved in political debates. However, others believe that supporting women's rights is not a political issue.

Meanwhile, the black tie around the Duchess's waist also got some attention, with some speculating that it was her way of showing her support for the #MeToo and #TimesUp campaigns.

"To the people criticizing the Duchess for her decision not to wear #MeToo black, note the ribbon around her waist," Sarah Burr wrote. "She OBVIOUSLY supports the cause and did so tastefully within her role as a Royal. Stop trying to drag her through the mud."

A number also called Middleton's critics to stop slamming the royal simply for not wearing black to the event. According to Mary Novaria, it doesn't help the women's movement to judge someone due to the color of her dress.

Meanwhile, Jamie Samhan created a poll asking her followers about Middleton's green dress at the BAFTAs. She asked them if the Duchess of Cambridge should have worn a black dress to support the women's movements.

As of this writing, the majority of the respondents said that it was not necessary for Middleton to wear black to show her support for women's rights.

Meanwhile, Middleton is an active advocate of mental health. As a mom herself, she is also campaigning for maternal mental health.

In fact, in January, the Duchess visited the Maurice Wohl Clinical Neuroscience Institute at King's College London. During the visit, she talked with the doctors about the challenges in dealing with maternal mental health issues like postpartum depression.
