Holly, 37, revealed the wardrobe mishap on her Instagram page.
She posted a picture of the offending outfit to her 3.4 million followers.
It consisted of a figure-hugging blue roll-neck top teamed with the checked ruffled mini skirt.
“The one that got away”
The blonde was also wearing point heeled white boots.
Holly told fans: “The one that got away #TooShortForTM,” followed by a crying emoji.
Her followers seemed disappointed she couldn’t wear the outfit.
One replied: “Love it! What a shame you couldn’t wear Holly.”
A third gushed: “Loving the legs Holly.”
Instead, the star wore a navy miniskirt, teamed with striped top and red boots.
Her followers didn’t seem to think she was that much more covered up though.
Holly’s recent Dancing on Ice 2018 final dress also caused a stir.
The presenter wowed viewers as she donned a racy frontless white dress.
