Hilary Duff says her style is "more fluffy" these days.

The 'Younger' star - who is expecting her third child - has just launched her Smash + Tess rompers and loungewear collection for mothers and their kids, and the busy mom has admitted comfort is key when she is choosing an everyday outfit, because she doesn't have a lot of time to plan what she wears.

Instead, the former 'Lizzie McGuire' star sticks to basic colours and styles them up with "fun" bags, shoes and statement jewellery.

She told Vogue: “I tend to dress a lot more fluffy.

“I don’t have a lot of time to spend putting a detailed outfit together. I want to be comfortable and to be able to move throughout my day, but still be on-trend. And that’s not always accomplished! But I like basic colours and accessorising with a fun bag and shoes. I love a big earring.

“I just bought this really cute Isabel Marant men’s blazer coat, it’s almost to the knee and it’s tweed.

“I roll up the sleeves and put it on top. And I have these square-toed boots—that’s how I wore one the other day.”

Hilary - who already has Luca, 8, with ex-husband Mike Comrie and two-year-old Banks with spouse Matthew Koma - admitted she was thrilled to be asked to design her own line because she was desperate to use her "creativity" in quarantine amid the COVID-19 pandemic.

She said: "When [founder Ashley Freeborn] reached out, it was probably two months into the quarantine in Los Angeles, and I had been a second grade teacher to my son for like 11 weeks - so I was like, hell yeah, I’m down to do something creative.”
