But, while she offered her opinion on the fashion piece, her own outfit had viewers at home talking.
The 45-year-old sent Twitter into a frenzy as she arrived in the studio in a plunging black gown, which allowed her generous cleavage to take centre-stage.
Those tuning into the ITV breakfast show were quick to comment on her glamorous appearance, with some asking if she thought she was heading to a dinner party.
One viewer tweeted: “Lady Michelle Mone dressed like she’s going to a dinner party #GMB.”
While another commented: “Where is Michelle Mone going or she not been home from club #GMB it’s 8am love not pm. (sic)”
“@MichelleMone Looking glamorous as ever today on @GMB,” a third shared.
Someone else demanded she return to the show again, writing: “@MichelleMone the voice of reason this morning on @GMB Looking lovely as always. You should have a regular spot on the show. Inspirational x.”
Michelle also touched on the subject of a second referendum in Scotland, which she believes is a terrible idea.
She urged Nicola Sturgeon to “stick to the day job” and focus on making healthcare and the education system better.
The lingerie tycoon added that the public were “sick of politics” and the Scottish Prime Minister should stop trying to force another referendum.
Good Morning Britain airs weekdays on ITV at 6am.
