After she shared her daily #HWstyle outfit picture to Instagram, viewers headed to social media to comment on the shot.
Some said she looked like a "sexy secretary" in the white Zara shirt and a Roland Mouret skirt.
However, others were stunned that Holly has actually worn both of the items before.
She wore the shirt on the show last week, while the presenter admitted the skirt was "an oldie but a goodie".
"A This Morning first for Holly today as she re-wore an outfit," said one ITV viewer on Twitter.
Another, perhaps sarcastically, added: "We all have to make sacrifices in these testing times."

In her post she advised her followers to take things "one day at a time".
"Always need the positivity at this time," one said.
"I’m scared but I love watching This Morning every day. Thank you for making me laugh every morning," said another fan of the show.
"Been tuning in every day since lockdown, you and Philip are a sheer tonic in these difficult times," another commented.
"Thanks for still being on This Morning during this time of distress. Honestly, you and Phillip couldn’t have done a better job," said another.
