Mosaic Brands' (ASX:MOZ) administrators are set to close 160 non-performing stores by mid-January of next year, multiple media outlets reported Tuesday.

As part of a consolidation program, the fashion retailer will close selected Katies, Millers, Rivers, and Noni B outlets, reports said. This came after Mosaic Brands closed 200 stores before it entered voluntary administration last October.

The closures will include all 80 Katies stores still open, effectively ending the brand, the reports added.
