The 37-year-old is delighted with the success of her eponymous label.
She has tried to keep progress slow, but was thrilled when her designs took off.
"Though I'm trying to take baby steps, the business is growing very quickly," she explained.
"Our turnover year-over-year has increased over 120 per cent. I think to anyone's standards that's very impressive."
Her collection has been worn by a host of stars including as Eva Longoria, Demi Moore and Cheryl Cole. However, Beckham clearly remembers industry figures warning her that starting a new fashion label was difficult.
"When I was starting out I remember Marc Jacobs saying, 'As long as the quality is great, then people can say it's not their personal taste, but they can't say that it's rubbish,"' she laughed.
The brunette beauty believes that the secret behind her success is her own personal approval. Beckham insists that she doesn't make a garment if she wouldn't wear it.
"Everything that I make, from glasses to a handbag to a dress, is something I would wear and carry myself,' she revealed.
"People ask who my customer is - I love to do in-store events with my retail partners, I love to meet my customers and get feedback - but I'm my customer."
