Gwen Stefani is launching a casual clothing line called DWP.

The No Doubt singer has teamed up with denim expert Michael Glasser to offer a fresh take on basic yet ''cool'' clothing to help women fill in the gaps in their wardrobes.

She explained to WWD: ''You have access to all these clothes from all your lines. It's like my dream, and a lot of it is stuff I actually dreamed up. But I'm always still missing those pieces and it's so annoying, and I don't mean to be greedy, but it's the same with everyone.

''I'm like, 'OK, am I really going to wear that again?' So this [collaboration] is about trying to find that piece that is super wearable but you still feel cool in.

''I was trying to get all the basics. Michael nailed the bottoms. For tops, I was trying to think about what I wear besides a tank top. I love cuffed-up sleeves, tops that are long in front and short in back. And we did a jumpsuit and a dress to fill in the gaps.''

Gwen's first foray into fashion came in 2004 when she launched her L.A.M.B. clothing line and she most recently teamed up with OPI for a signature nail polish range.

The singer also admitted her style-savvy sons, Kingston, seven, and Zuma, five, have an unrealistic approach to fashion because they have been ''spoiled'' by her lifestyle.

Gwen said: ''I've been spoiled being in the fashion business. My son will be like, 'Mommy, 20 new pairs of shoes came today. How come?'

''Because I'm always telling him it's not normal to have 20 pairs of tennis shoes to try on before school. People have like one or two. But at our house...''
