Dark green is the new black for former Melbourne socialite Simone Semmens, who has swapped her designer wardrobe for a prison uniform after being convicted of evading $1.85 million in GST on the sale of several luxury homes.

A County Court jury found Semmens guilty on all 10 charges of dishonestly causing loss to the Commonwealth on June 21, before she was remanded to the high-security Dame Phyllis Frost Centre in Deer Park.

The former Channel 7 newsreader turned property developer will be sentenced after a plea hearing on July 30.

During a three-week trial, the jury was told the one-time beauty queen had evaded GST on the transfer of 10 properties between 2001 and 2007, despite telling her accountant and bank manager she was aware of her tax obligations.
