Nicole Richie isn't trying to "prove" anything with her fashion lines.

The former socialite - who runs House of Harlow 1960 and Winter Kate - admits her ranges will not "please everyone" but she knows how hard she works to get clothing out in the world she knows she loves.

She told website "It's not about proving myself to anyone. At the end of the day, you can't please everyone. You have to do things for yourself. I have had many moments in life where I haven't gotten credit for the work I've done. And that's OK with me.

"My process is still the same. I work very hard, and am serious about my work. That stays true whether anyone sees it or not."

Style-conscious Nicole now believes choker necklaces are due a "comeback" and expects people to be wearing them regularly soon.

She said: "I went through a serious choker phase. I used to make them for my friends at school. I have a feeling they are going to be making a comeback very soon. Mark my words!"

However, she also thinks there are "no rules" when it comes to accessories and people should be allowed to wear whatever they choose.

She said: "Accessories speak volumes when it comes to a person's wardrobe, especially when one is dressed down in jeans and t-shirt. So have fun with it-there are no rules."
