The 28-year-old has designed the new range of evening dresses for British retailer Next - the collection will be called Geri by Next.
She unveiled the collection in London on July 27 and even donned a navy blue one-shouldered dress herself, with a group of models wearing some of the other designs.
The collection is the second she has designed for Next as she had previously worked with them on a swimwear range.
According to UK newspaper Metro, she spoke about the dresses: 'I've been sketching everything myself and I'm thrilled with the results.
'I've had the opportunity to make dresses that are not stupidly expensive but still elegant enough to wear to an upmarket event.'
