Dressed in her usual attire, the 38-year-old opted for a long-sleeved red top paired with a midi-skirt which synced her in around the waist.
Looking stunning as usual the blonde beauty wore her bob down and opted for minimal makeup.
But due to being under a mass amounts of lights, from some angles, Holly’s top appeared to turn see-through.
Revealing her white bra, some fans weren’t left too impressed while others encouraged trolls to “give her a break”.
Taking to Twitter, one viewer tweeted: “All the stylists on This Morning and still Holly doesn’t know not to wear a white bra.”
Another said: “Distracting see-through top there.”
A third wrote: “Has Holly got a white bra on? It’s showing through.”
One more commented: “Holly’s bra showing through again lol.”
However, some fans urged trolls to “let live”, one hit back: “Oh give Holly and her bra a break and let her live.”
Earlier in the episode, viewers were left “horrified” as a life-like robot called Sophia made an appearance on the show.
The robot appeared on air to unveil her newest skill, that she’s learned how to draw but Holly was much more interested in finding out if Sophia could turn on them.
The conversation quickly freaky after Holly asked David if Sophia could turn on humans if she got smarter.
An awkward David replied: “I don’t think so.”
To which Holly and co-host Phillip Schofield gasped: “You don’t think so?”
The robot then smiled and stared at Holly, who screamed: “Oh, that’s a creepy smile.”
This Morning continues weekdays at 10.30am on ITV.
