Kim Kardashian would consider designing a maternity line.

The reality star and her sisters Khloe and Kourtney are busy with their new Spring 2014 Kardashian Kollection for Lipsy, but would investigate the possibility of creating clothing for mothers-to-be in the future.

Kim - who has eight-month-old daughter North with her fiancé Kanye West - told LOOK magazine: ''We're focusing on our current lines, including our new children's range which hits stores this spring - but who knows, never say never!''

The 33-year-old star believes their new line is perfect for the new season with its mix of bright prints, monochrome jumpsuits and curve-clinging dresses.

She explained: ''For Spring, I'm putting together a clean, classic and feminine wardrobe. I love the long-sleeved white mesh crop top. There's a matching skirt, and it looks so simple and sophisticated on.''

Kim says her favourite piece for a night out with Kanye has to be the nude body-con dress, which she would accessorise with simple and elegant jewellery.

She added: ''Our nude body-con zip dress is perfect for date night. Nude is such a sexy yet understated colour and the shape is incredibly flattering. Wear it with simple accessories to let the dress stand out on its own.''
