Because it’s that easy.

Getting to know: Miuccia Prada

On trend for autumn-winter 2014-2015: tax probes. Milan-based fashion designer Miuccia Prada, the woman behind the Prada and Miu Miu lines, and her husband

Patrizio Bertelli

, have been told by Italian tax authorities that they are looking into “the accuracy of certain past tax filings by them as individuals, in respect of foreign owned companies”.
