Dannii Minogue puts on a leggy display in a satin minidress as she joins the stylish Shaynna Blaze at the Melbourne Fashion Festival.

Dannii Minogue and Shaynna Blaze showed off their fashion credentials as they stepped out at the Melbourne Fashion Festival on Wednesday.

The singer, 52, and The Block judge, 60, pulled out all the stops to ensure they turned heads at Suit Up Runway at the Royal Exhibition Building.

Dannii put on a leggy display in a white satin minidress with a dramatic neckline, worn over a black bra with sparkling silver cross-straps.

She added a few extra inches to her figure with a pair of black platform heels adorned with jeweled bows.

The I Kissed a Boy host added dramatic eyeliner to her stunning features as she posed up a storm for the cameras.

She was joined by fashionista Shaynna, who looked as stylish as ever in a black dress with statement puff sleeves and a daring split skirt.

The interior designer let her outfit speak for itself as she kept her accessories simple with a pair of delicate drop earrings.

She added some extra frame to her height with a pair of strappy black heels and looked in good spirits as she enjoyed a drink with Dannii.

The couple avidly watched the Suit Up runway, where conservationist Robert Irwin made his runway debut while showing off a variety of designer pieces.

According to a description of the event, Suit Up Runway shows how Australian designers have playfully reinvented the suit “in a variety of shapes, colors, fibers and patterns.”

“The looks feature stunning intricate embroidery, bold pieces and celebrate inspiring designers with incredible personal stories,” the description adds.

Also attending the show were the likes of Masterchef Australia star Khanh Ong and his best friend, The Bachelor’s Matt Agnew, and Chantelle Otten and Dylan Alcott.

It comes after fans were first treated to Dannii performing I Kissed A Girl in a trailer, following the success of the gay male version of the show I Kissed A Boy.

While no specific release date has been confirmed, the BBC Three series will officially arrive “soon” and will see ten women live together in a luxurious Italian house in the hope of striking up a romance.

Producers have promised that the new series will “serve drama, break stereotypes and promise more twists and turns than ever before.”

The unique twist on the I Kissed A… format sees contestants share a kiss with their partner before saying a word to each other, while Dannii plays Cupid.

Couples are matched based on what they are looking for in a partner, and their chemistry is immediately tested to see if that first kiss will lead to love.

I Kissed A Boy was released to rave reviews last year, but presenter Dannii revealed on Stellar magazine that lost followers for hosting the gay dating show.

The pop star, who has always been a vocal ally of the LGBTQ+ community, said: “It really made me laugh when I read the comments from people saying, ‘I’m going to unfollow you.’

‘I just thought, well, that’s strange. Haven’t all the other things I’ve done within the queer space been a problem for you?
