In fact, the floral two-piece was so expensive, viewers said they "only wish" they could afford to copy the presenter's style.
Uploading her usual #HWstyle photograph to Instagram, Holly revealed she was wearing a pretty pink co-ord by Tabitha Webb.
The Iris skirt retails at £200, while the Dora pussy bow blouse retails at £295.
"Love this outfit, but I'd like to make a complaint," one follower commented on Holly's Instagram post.
"Can you please wear some more affordable outfits on occasion?" they added.

The woman then claimed that Holly gets "paid to wear these designers".
She continued: "But it would be nice for once to admire an outfit that's been bought from Next, Marks And Spencer, Monsoon or Fat Face even."
Went to go and see if I could afford the outfit. Blouse alone is £295.
The woman went on to point out that This Morning features "reasonably priced things when the show covers fashion".
However, she added: "I was horrified that today's outfit is just under £500 to buy."
One said: "So so pretty. Went to go and see if I could afford the outfit. Blouse alone is £295."
The woman added: "May have to give that outfit a miss as having our baby in three weeks."
Another said of the pricey ensemble: "Love love the dress, Holly – beautiful. But I can only wish."
"Love this beautiful print, looks gorgeous on you Holly," said another. "But unfortunately a bit expensive for most of us."
Later in the show, it appeared Holly had ruined the outfit, as a piece of chicken jumped out of the wok during the show's cooking segment.
It landed directly on the £200 skirt.
"That's a shame," she said.
