Pip Edwards is every inch the doting mother as she accompanies son Justice Single to Year 12 formal

Pip Edwards put on a very leggy display as she stepped out in a short polka dot dress to attend her son Justice Single's Year 12 formal.

The P.E Nation co-founder, 44, snapped some doting mother-son selfies with the 17-year-old for Instagram on Tuesday as he wore an all-black suit from Emporio Armani.

Meanwhile, the teenager's famous mother stole the show in a short A-symmetrical gown from Romance Is Born, slicking back her blonde tresses.

'Getting all dressed up for my son's year 12 formal,' the fashion designer said as she highlighted her genetically blessed features with some makeup.

'My handsome man looking so gangster in his suit,' she added alongside a photo of her only son.

Pip shared another photo of herself posing with son Justice and his date for the formal, Daisy Brown, writing: 'Love you two so much.'

The socialite paired her sleeveless dress, which featured a high neckline, with a pair of matching black and white pumps.

She completed her look with a gold bangle and watch before slipping a pair of chunky gold earrings for the milestone occasion.

It comes just days after Pip took a savage swipe at her ex-boyfriends in a scathing new interview.

The fashion designer spoke to Stellar Magazine last week and insisted she does not understand the public interest in the men she dates.

'I don't know what's so interesting about my boyfriends. I think I'm more interesting,' she said with a laugh.

'Respect to the ex-boyfriends, but there are way more interesting things and more layers to me than that.'

Pip said that the concentration on her dating life 'doesn't even touch the sides'.

'It's kind of like, why aren't you seeing the woman that's had an incredible career trajectory in an industry, worked for some incredible businesses, made some kind of inroads, raised a child on her own, independently, financially, who's a great friend, who's got energy?' she said.

'I mean, I know I'm talking about myself here but I kind of have to—because all of that gets wiped by some man that I happen to have some experience with.'

It comes after Pip seemingly confirmed her new romance with disgraced multimillionaire businessman Geoff Bainbridge during a very cosy outing in New York in September.

The Aussie fashion designer had been spending time in the US in recent days where she started her new role with Aussie label Ksubi after stepping down from her activewear brand P.E Nation.

Wealthy executive and father-of-four Geoff, 52, joined Pip on the the trip, and the pair appeared to officially debut their romance when they packed on the PDA in Soho.

Geoff made headlines over two years ago when he resigned as the chief executive of alcohol business Lark Distilling .

He is a prominent early investor of popular burger chain Grill'd, but left the business in 2015.

A source confirmed to Daily Mail Australia that Pip and Geoff are 'dating'.
