It was barely a month ago that Jessica Bratich-Johnson gave birth to her first child Rubika Anne with cricketer husband Mitchell Johnson but that has not stopped her from pushing ahead with a new fashion venture.

Bratich-Johnson, who launched her handbag line Jessica Bratich a year ago, has teamed with four other emerging WA designers for Fashion Cinque, an edgy concept pop-up store in Brookfield Place.

Located in the old Newspaper House on St Georges Terrace, the industrial-style space features the creations of Bratich-Johnson along with labels Steph Audino, The Little White T-Shirt Company, Siss On Bare and Jonte.

"It's a good opportunity to have our stuff in the city and approach a different market," she said.
