Hilary Duff dons a sheer black skirt in New York to pre-film her appearance on Late Night with Seth Meyers

Hilary Duff stepped out of her Manhattan hotel on Thursday wearing a black mid-length skirt that was so sheer you could see her panties underneath.

The 36-year-old mother of three’s blonde locks were tucked into a black cable-knit sweater and she wore matching slingback pumps, chosen by styling duo Brit + Kara Elkin.

Hilary, who sported a bright red pout, completed her daytime outfit with a $4,450 Loewe Nappa Lambskin Medium Squeeze bag.

Duff then headed to 30 Rockefeller Plaza to pre-tape Thursday’s episode of NBC’s “Late Night with Seth Meyers.”

The producer and star of “How I Met Your Father” has been hard at work promoting her 32-page children’s book “My Little Sweet Boy,” illustrated by Kelsey Garrity-Riley, which went on sale Tuesday.

Hilary – who previously wrote the 2021 book “My Little Brave Girl” – added a line to the book that read: “When you feel your feelings, let your tears flow.”

“I think there’s so much power in that, when you have access to your emotions,” Duff told CBS Mornings on Tuesday.

“I know with my journey [my son Luca Cruz Comrie] It’s like, “Come on, be tough!” Stand up! You’re okay!” I kept hearing that and thinking, “Maybe he’s not feeling well right now.”

“Who am I to say he should be fine, or to tell him he’s not fine at this moment?” And he’ll learn to be in control when he’s older, but why Let’s try to suppress and bury this right now… I want him to feel the power of his whole self.

The Texas-born blonde was the mother of the 11-year-old boy during her six-year marriage to Mike Comrie, which ended in 2016.

Hilary and her second husband – Winnetka Bowling League frontman Matthew Koma – are the proud parents of five-year-old daughter Banks Violet Bair and two-year-old daughter Mae James Bair.

Duff was technically still married to the 43-year-old retired NHL player when she met the 36-year-old “Breakfast for Dinner” singer while collaborating on her 2015 album “Breathe In.” Exhale.

The OLLY paid partner and Matthew split for six months in 2017, but they will celebrate their fourth wedding anniversary on December 21st.
