Australian-based firm Miller's Retail Ltd is to acquire the Silhouette women's clothing brand for A$5.3 million, as the latest step in its acquisition policy, it was revealed on Wednesday. The Silhouette business, which currently trades from 52 Australian stores, will fit in well with Miller's existing womenswear products, said managing director Ian Miller, who pointed to Silhouette's strong profit history as an excellent reason for acquiring the brand.
