Dasha has spent several days in the resort, and was photographed days ago partying with her friend, Italian beauty Giovanna Engelber, who is the creative director of Swarovski at the five-star Kulm Hotel in St Moritz.
In images shared on her Instagram page yesterday, the glamorous brunette posed in a blue mini dress which skimmed her thighs and featured trendy feather detailing across the sleeves.
Among the snaps was a rare photo with her billionaire shipping heir husband Stavros Niarchos, 36, whom she married in St Moritz in January 2020.
