The shop had been the head office, studio and showroom for the renowned designer throughout her extensive career.
Mrs Davenport said retail had changed with the access to the internet and they would no longer need the infrastructure.
‘We have resisted the change for a long time,’ she said.
‘It is all part of a journey, we have been offered so many amazing opportunities and things needed to change.’
Dressing the likes of Judith Durham and Carmen Lawrence, Mrs Davenport said that initially closing the store was a very difficult decision to make.
‘You enjoy the routine,’ she said.
The label will continue to expand as Mrs Davenport prepares to launch her collections into duty free sales, in-flight shopping and purchasing on airlines and cruise liners.
‘Perth is so remote and to take on the northern hemisphere on such a level is the ultimate dream,’ Mrs Davenport said.
Alongside her brand, Mrs Davenport has worked extensively with more than 200 charities.
Currently the label is helping raise money for Zonta International, an organisation that aims to improve the status of women.
Only two stores will remain in Applecross and Queensland and Mrs Davenport will continue her on-line store, as well as her fundraising sponsorship projects.
‘It is all so rewarding, I don’t wish to stop,’ Mrs Davenport said.
