Nicole Richie won't tell her friends where to buy the best vintage clothes.

The Fashion designer - who is Lionel Richie's daughter - admits she can be ''selfish'' when she finds out a great place to purchase second-hand garments and would always rather keep it to herself.

She said: ''Well I'm very selfish and I like to keep where I find my vintage clothes a secret.

''I'm constantly looking for the local Flea markets, some cool underground places. I'm really just looking for something that represents me.''

Nicole - who has daughter Harlow, four, and two-year-old son Sparrow with husband Joel Madden - claims she never looks at the label when she buys clothes because she just wants items that feel good on her.

She told Britain's OK! magazine: ''I'm always one to never really focus on the actual label.

''I dress for myself and I encourage women to do the same. I don't buy myself something because it looks good on a hanger and has a high price tag. I shop at thrift stores all the time and every time I go to an event, I'm not buying a new dress.''
