The TV presenter uploaded her daily #HWstyle shot and it was a resounding yes to the dress from her Instagram followers.
Holly wore a high-neck BA&SH at Iris Fashion black crepe dress printed with white flowers.

Her LBD showed off her toned and tanned pins thanks to its high-low hem.
The dress is available online in sizes 0–3 – which is equivalent to UK sizes 6 to 12.
It costs £240 and, although it's pricey, the designer describes it as a "desk-to-dinner" dress – meaning you'd only need to buy one outfit instead of two.
That's how we'll be justifying the spend, anyway!
"Design duo BA&SH paint a vintage '30s silhouette with a Japanese-inspired floral print for this desk-to-dinner worthy dress," said the blurb.
"Kept elegantly demure, the Poppy features a ruffled collar, button fastenings on the shoulder, short puff sleeves and an elasticated shirred waistband," it added.
The website continued: "Its high-low hemline adds to its feminity."
And the dress certainly caught the attention of Holly's followers, with many saying the star looked "beautiful".
"You look beautiful," said one.
"Such a pretty dress," said another.
"This dress is so pretty," another fan added.
I love both the dress and the person wearing it!
"Absolutely love it!" said one style fan.
"You look gorgeous, love your dress," another commented.
"I love both the dress and the person wearing it," declared a Holly super-fan.
