She is knows for her long flowing curly brown locks. 

But Married at First Sight's Belinda Vickers has switched up her look.

Posting to her Instagram Stories on Monday, the 29-year-old shared a picture of herself with her hair tied into a big bun.  

She also included a poll on the post, asking fans whether or not her bun was too high.

Throughout the series, fans were used to seeing Belinda with her long ringlets resting over her shoulders. 

At one stage, she styled her thick mane into two pig tails resembling a look of the 1990s.

Belinda and her partner Patrick Dwyer, 27, are one of the few couples to have emerged from this year's season of the hit reality show still together.

'After everything, we made it,' Belinda posted on Instagram on Sunday, sharing a photo of herself and Patrick at the reunion special.

Added Patrick: 'Holy Moly Guacamole. What a ride this experiment has been. I'm so grateful to have met you Bel. I love you'.  

While her hair was a topic of conversation throughout the season, Belinda was also renowned for her eccentric ensembles on MAFS, which saw her donning a variety of costume-inspired looks.

For the show's final dinner party, she stepped out in a pair of orange, maroon, white and yellow floral print flares, which she teamed with a matching crop top.

Meanwhile, Patrick stepped out in a matching button-up shirt fashioned from the same fabric.  

The pair revealed their baby plans just days over the season finale aired on TV.

Belinda told Woman's Day magazine: 'I definitely think Pat would be a great dad, there's no doubt in my mind.'

'We've talked about it. I definitely want them [children],' Patrick added.

'I joked about it [marriage plans] last week and she freaked out... so I was like, "Okay, I'll wait a bit,"' he added.

Patrick and Belinda were one of few couples this season to get their happily ever after.

Married At First Sight will return on Channel Nine in 2022.
