( CNN ) -- Fashion luminaries Domenico Dolce and Stefano Gabbana were sentenced to prison in Italy Wednesday for failing to pay 40.4 million euros in taxes to the Italian government , their lawyer and a prosecutor said . `` This time it was not the case like the invoice for car repair , '' prosecutor Laura Pedio said of the crime for which the fashion duo was convicted . `` This time it 's serious , complicated , sophisticated tax fraud crime . '' Both men were sentenced to one year and eight months in prison and , in addition to what they owe in taxes , told to pay a fine of 500,000 euros . Their lawyer , Massimo Dinoia , vowed that the defense plans to appeal the convictions as well as the related fines and sentences . `` Dolce and Gabbana will not go to jail now or ever , '' Dinoia said . Dolce & Gabbana , fashion 's golden duo . Four others associated with the upscale Dolce & Gabbana brand -- including Domenico 's brother Alfonso Dolce and company tax consultant Luciano Patelli -- also face prison time , though Dinoia and Pedio did not know the length of all their sentences . While the decision was announced Wednesday morning in a Milan court , authorities did not immediately release details to the media or public . According to Pedio , investigators found that between 2004 and 2007 Dolce and Gabbana failed to tell Italian authorities about an offshoot company they 'd set up in Luxembourg , costing Italy millions of euros in taxes . `` I 'm very satisfied with the sentence , '' the prosecutor said . `` It was a very elaborate ( use of an offshore company ) that appeared legal , but was illegal . '' The fashion magnates ' defense team said this was n't a sweeping verdict . In a statement , the lawyers said the court found Dolce and Gabbana innocent `` of the accusation of having unfaithfully declared their earnings , '' even as the two men were convicted on a `` taxes declaration omission . '' It 's not clear how the court ruling will impact the storied Dolce & Gabbana company , if at all . The two stylists debuted their brand in an October 1985 show in Milan . Since then , they have exploded to become one of the world 's most recognizable and desired fashion companies , with an array of products and stores from Azerbaijan to Qatar to Singapore to the United States and many places in between .
