Oh dear! Ali Oetjen suffers a major wardrobe malfunction as she steps out in a plunging suit dress and stiletto heels at the Doomben Races

She rarely puts a foot wrong when it comes to her fashion choices.

But on Tuesday, former SAS Recruit Ali Oetjen suffered a wardrobe malfunction as she celebrated the 2020 Melbourne Cup at Doomben Racecourse in Queensland.

The 34-year-old reality star appeared to have forgotten to remove the stickers off the bottom of red stiletto heels.

The shoes’ size labels were visible as the blonde star made her rounds around the racecourse. 

The former Bachelorette decided to go braless for the ritzy occasion, flaunting her cavernous cleavage in a plunging suit dress.

Ali complimented her daring outfit with black wide-brimmed hatinator, box clutch bag and red stilettos.

The blonde beauty had her long tresses straightened, which she wore down and out.

She accessorised her look with red lipstick and a crystal pendant necklace.

It comes just days after Ali took to Instagram to share photos of her trying on outfits ahead of the races.

Ali left very little to the imagination when it came to her decolletage.

She first showed off a coral pink mini dress with a gaping neckline that exposed her ample assets, which she made sure to cover up on Instagram with a black square.

After a day of trying on dozens of outfits, she revealed that had chosen her outfit for race day – but kept it under wraps.
