Princess Olympia partied the night away when she flew to the Isle of Bute to celebrate the 25th birthday of Lady Lola Bute at her family's estate last week.
The American-born Greek princess, 27, enjoyed an evening of frivolous fun wearing a pair of black split-leg flares with cobalt piping. She paired the trousers with the matching top - a jacket-style top which had the same royal blue piping around the hem and on the pockets.
