Nicole Richie hates wasting money on clothes.

The designer is wary of brand new trends and prefers to invest in classic pieces she can wear time and again, which she sees as a much better investment.

She explained: ''I personally tend to go with clothing I can wear season after season and get a lot of wear out of as opposed to something that's trendy that I have to throw out later on. I feel like it's a waste.''

The boho style icon is excited about the warmer weather and has been adding lots of brights and prints to her wardrobe.

Nicole quipped: ''Summer is the season to wear a ton of it! My favourite is yellow, but I really like mixing prints.''

The star - who boats two jewellery lines, Winter Kate and House of Harlow 1960 - also admitted nothing makes her happier than seeing other mothers wearing her creations on the school run with her children, Sparrow and Harlow.

Nicole added in an interview with Us Weekly: ''I get excited when I'm pulling up to school and I see a mom wearing my things and they don't even know that it's mine. That's really exciting for me.''
