Clothing retailer Mosaic Brands is counting the cost of selling useless hand sanitiser and dodgy face marks at the height of the coronavirus crisis.

The retailer, which owns clothing chains Noni B, Millers, Katies, Rockmans, Autograph and Rivers, has been forced to pay penalties of $630,000 after admitting to breaching consumer laws by making false or misleading claims about hand sanitiser and face masks advertised on its websites and via direct marketing between March and June last year.
