Nicky Hilton Rothschild came up with new children's clothing line when pregnant with first daughter

Nicky came up with most of her ideas for the collection - which features matching women and children's garments - when she was expecting her oldest child Lily and the majority of the prints are inspired by photos taken on her iPhone.

The 'Bijou top' from the collection was inspired by the tiles in a Positano villa she and her family stayed at and the 'Kate Mediterranean blue' fabric design was inspired by the vibrant patterns from a trip Mykonos.

Speaking to WWD about the brand's move into the kids clothing market, Nicky - who also has daughter Teddy with her husband James Rothschild - said: "I came up with the idea when I was pregnant with my first daughter and I came to them about this mommy-and-me idea. They [Tolani] had never done children and they loved the idea so I worked very closely with them in making all of the different prints. Most of them were taken right off my iPhone."

Nicky commented that the culture of "sharing" played a part in her desire for a collection that can be worn by both children and adults. She said: "We live in a culture where everyone is sharing everything. They're sharing videos. They're sharing family moments, work milestones, their children and they like dressing them up."

She also revealed that it was "important" to her to steer away from "expensive" clothing when creating the line, as well as pieces that aren't machine washable.

Nicky said: "I wanted to create a line that was stylish and comfortable with reasonable prices and I made sure that all the children's pieces were machine-wash-friendly because who wants to send baby clothes to the dry cleaner?"
