Two world famous Italian fashion designers may soon be wearing prison grey.

Domenico Dolce and Stefano Gabbana are facing possible jail sentences for alleged tax evasion.

A Milan prosecutor says the pair should  be jailed for two and a half years for alleged tax evasion.

Dolce and Gabbana are accused of not declaring taxes on royalties of about $1.35 billion in one of the few high-profile tax cases to go to court in Italy.

The designers deny the charges.

Prosecutors say the two sold the D&G and Dolce&Gabbana brands to a shell company  set  up in 2004 in Luxembourg, to avoid paying taxes in Italy – where corporate tax rates are some of the highest in the world.
