An 'aggressive' collector of Real Housewives Of Melbourne 'memorabilia' is suspected of stealing a $25,000 dress worn by Gamble Breaux to the 2017 Logies.

The Alin Le'Kal dress worn by Gamble was the only item taken from the designer's Collingwood boutique, located in Melbourne's inner suburbs, when it was broken into on Tuesday night.

'I feel sick because I know how much work went into it, because you can't recoup those losses - something like that can make or break a designer,' Gamble told Daily Mail Australia on Wednesday.

The Real Housewives star wore the custom made designer piece to the Logies in April.

The socialite later made headlines when a reporter chipped her tooth while interviewing her on the red carpet.

While stopping short of saying she knew who the person was who took it, Gamble said she suspected the culprit was someone who 'is known to all the housewives'.

'I would call them them a stalker now if it is that person - it is someone who is a collector of housewives memorabilia and is quite aggressively into it,' Gamble said.

'And look there is Logies dresses and there is Logies dresses, but that one got a bit of press because a reporter knocked my teeth out when I was in it on the red carpet ... so that might be why it is more collectible than others.'

Designer Alin Le'Kal has been left 'baffled' and angered by the robbery, which occurred just three weeks after the brand moved into its new boutique.

Custom made: Gamble's gown had taken three months of handwork and Alin hoped whoever took the gown realised how valuable it was to him

After being worn by Gamble on the Logies red carpet, the dress had been displayed in prime position in the store's front window since its opening.

'We are just totally baffled, at this stage we have no idea why, it's so random,' Alin said.

Gamble's gown had taken three months of handwork and Alin hoped whoever took the gown realised how valuable it was to him.

'We work hard for garments and to provide a service to clients that it exclusive,' he said.

'For someone to do that it is just reckless and rude, I've never been so offended in my life to be honest.'
