The fashion designer gained inspiration for the scent, Nicole, by the "many different layers" of fragrances her mother used to wear when the reality TV star was a child, and as a result she particularly wanted amber, cashmere woods and vanilla smells to feature in the fragrance.

She said: "I have a very traditional Southern mom - you never left the house without lotion. Over her lotion went oil and perfume - she was very put together from head to toe. It wasn't just a one-dimensional smell - there were many different layers."

Nicole's scent also contains hints of Seville orange, Moroccan rose, lily of the valley, sandalwood and sugared patchouli, with bottles available for $55 and $69 and will be available in September. The 30-year-old star was keen for the outer box of her scent to represent "different layers of a woman", which she also tries to embody with her women's clothing and jewellery lines Winter Kate and House of Harlow 1960, named after her four-year-old daughter, Harlow Winter Kate Richie Madden.

She added to WWD: "I wanted it to represent different layers of a woman, which is what I try to do with Winter Kate and House of Harlow 1960.

"I'm very particular in the way that I create. We're in an interesting time right now where women aren't just one thing - there are many different parts to a woman. So I wanted to create a very intricate bottle that was still elegant, but not so in-your-face girly at the same time."
