The 35-year-old - whose outfits on the ITV talk show go down a storm with viewers - showed off her enviable curves in a high-waisted yellow skirt, which she teamed with a sleeveless white blouse.
The bubbly blonde - who recently admitted she's a huge fan of her nickname 'Willoughbooby' - had her toned pins on display and added some extra height with a pair of strappy nude heels.
She wore her locks loose and wavy and completed the chic look with a slick of pink lipgloss.
As per usual, Holly took to Instagram to share a snap of herself in her latest get-up, with her sharing two images alongside the caption: "Tuesday's look on @itvthismorning ... @trinnylondon is doing lace today so I thought I'd join in! Skirt by @anthropologie and shirt by @bananarepublic."

They're not known for keeping straight faces while showcasing their presenting skills, but Holly and Phillip did a pretty good job this morning, despite Holly later being snapped in fits of giggles as she practiced her gardening skills.
The pair were hosting a segment on topiary with guest Charlie Bloom, and as usual, they made sure it was littered with cheeky innuendos.
Referring to the rainy weather as they stood outside under a marquee, Phillip announced: "This is the perfect day to trim your bush."
As Charlie talked them through the art of trimming bushes in June, she also made sure to make plenty of jokes which led Phillip, 54, to say: "You're good, you can come back."
It was then Holly and Phillip's turn to have a go at trimming bushes, as Charlie set them a task of making a heart shape.
The much-loved duo were only given 45 seconds to do so, and Holly ended up winning the challenge after Phillip "cut into dead wood".
As Phillip inspected both bushes, he declared: "I went mad on my unruly bush!"
This Morning continues weekdays at 10.30am on ITV.
