Meghan Markle is not afraid to make a fashion statement, but her updo during her first royal event with Prince Harry for 2018 may have been a miss.

The "Suits" star opted for a messy bun hairstyle when she visited Brixton with her fiancé. Markle was all smiles as she waved to the crowd, and fans noticed her hairstyle as there were loose strands framing her face. Some have expressed their disapproval of how Prince Harry's future bride styled her hair during the visit, with one Twitter user calling it an "untidy topknot."

"The untidy topknot was not becoming," Judy wrote. "Ok these two need to grow up they aren’t teens or in their 20's anymore. Harry is early 30's and Meghan is almost 40. She can't keep pushing the envelope, eventually the Queen is going to step in and take her to task. We need dignity."

Another user, who loves Prince Harry and Markle, also believes that the "Horrible Bosses" stars should have a more presentable hairstyle when she represents the royal family. "I love Harry and Megan. Such a great couple. But Megan's going to have to lose the tasseled hair styles for photo opts as a royal family rep," the user wrote on Instagram.

"She needs to do her hair," another user wrote.

"When is Meghan getting a coach or at least hairstylist/wardrobe help??" another critic commented (via Little Things).

"How many princesses, queens, etc., do you see going to an event in a messy no shampoo day bun?" another Instagram user said.

However, while some gave Markle's messy bun a thumbs down, there are also some who loved it, commenting that Prince Harry's fiancée pulled off such an effortless hairstyle.

"Love her casual hair style," Instagram user melsnotebook wrote.

"Meghan looks gorgeous! I love her hair!" another said about Markle's messy updo.

Another user defended Markle's choice and deemed it as "fine" and "perfect for the occasion." Rebecca Watson also believes that the messy knot wasn't inappropriate given that the actress will not be a queen like Kate Middleton.

"I think it was appropriate for the visit they made - it was casual. And as you say, she won't be queen. Catherine will," the user wrote.
