The presenter, 38, wore a burgundy knitted jumper from Whistles and a matching pair of leather trousers from Kate Spade New York, which cost £895.
Holly finished the look with a pair of burgundy suede heels.
Holly captioned the post: “Morning Tuesday… let’s do this!!!!”
Fans were divided over the outfit, with many not keen on the trousers.
One person commented: “Oh dear, sorry don’t like that look. If you are cold, then bring back the skirts and tights as those suit you much better.”
Another wrote: “Not keen on the trousers,” while a third said: “I don’t think the trousers would be flattering on anyone, not a fan I’m afraid.”
Others loved the look.
One said: “What’s with people’s negative comments? That outfit looks fabulous on you @hollywilloughby.”
Another wrote: “Those trousers are fantastic,” while one added: “Love the outfit and colour on you.”
Meanwhile, on today’s show, Holly and co-star Phillip Schofield left viewers in hysterics as they tested out umbrellas with a wind machine.
I don’t think the trousers would be flattering on anyone, not a fan I’m afraid.
The pair were joined by Alice Beer, who presented the best brollies to keep you dry in the rain.
But when they tested the umbrellas against a wind machine, Alice was left blown into a wall and Phil’s umbrella hat was whisked off his head.
