The blonde beauty flaunted her slimline frame in the fitted frock, which featured a two-tone checked design with a quirky velvet on the side of the dress.

Covering parts of her face with her mane, Pixie dressed her platinum blonde locks into a curly updo.

She upped the ante in the makeup department as she opted for a slash of brown matte lipstick, paired with orange glittery shadow applied to the perimeters of her eyes.

Pixie recently revealed that she is planning to marry her boyfriend Oliver Cheshire in September next year after nearly seven years together. 

She said: 'You can set a quick turnaround, it can be done. Christmas will be a good time to sit down and actually talk about it.'

The blonde beauty added the pair are hoping to have two weddings - one in the countryside and a smaller in a 'hot country'.

'We want to be in the UK for sure, because we have a big family and want everyone to be involved. Probably in the countryside somewhere.

'We haven't seen any venues yet, we need to get down to that and find one really special.

The pair got engaged last year, with Pixie exclaiming that it was the 'biggest surprise ever' as she showed off a dazzling diamond ring, adding simply in the photo's caption: 'So happy.'
