Her legion of fans went into bat for the star, who expressed shock that anyone could find fault with the look - and poured praise on Barry's appearance.
"She's jealous of those traps," one suggested, with another agreeing and saying the much-loved presenter "looks pretty buff".
"I'm not sure what the issue is. Gorgeous colour, style, and Hilary could pull off wearing a potato sack," a fan gushed.
Others wanted a bit more Barry for their buck, with one commenter saying they could "handle a bit more showing" and another saying the complainant just "wanted more cleave".
This most recent complaint is the latest in a long line of similar gripes about Barry's fashion choices, with Barry herself sharing a photograph showing her wearing this top in the past.
In December last year, Barry taunted her critics on Instagram when she shared a pic of the outfit.
"Some might accuse me of deliberately dressing like this to wind up Ken, Geoff and Barbara. They're not wrong," she captioned the photo.
"#dressingmyage #shoulderslut".
The TV host has repeatedly called out critics who found fault with her outfits.
Last year a social media user wrote on Instagram: "Good god, Hilary! What are you wearing tonight? Looks like something you picked up at an op shop? Get some style advice, girl."
However, the man was swiftly put in his place.
"Piss off, Ken," she replied, then sharing her response to her Instagram followers.
Earlier in the year, Barry was told "dress properly" by a man on social media.
He was referring to another off-shoulder top Barry wore while hosting Seven Sharp with Jeremy Wells.
"Please encourage Hilary to dress properly. Exposed shoulders are for the young," the man wrote in a Facebook post to the show.
Barry called out the man's age shaming.
"Just for the record, I'll wear what I like, when I like."
She then posted a photo of her basking in the sun on a beach in togs, with a message of empowerment to other women.
"This is for every Geoff who ever told a woman what to wear or what part of her body to cover up. We will not be told. Not now. Not ever."
