Mary-Kate Olsen Joins Fiance Olivier Sarkozy at Take Home a Nude Benefit

Mary-Kate Olsen poses for a photo with fiance Olivier Sarkozy while attending the 2014 Take Home a Nude event held at Sotheby’s on Thursday (October 9) in New York City.

The day before, the 28-year-old fashion designer was seen bundled up in bright accessories while leaving her building. She was wearing her Cartier engagement ring on her index finger that day, perhaps to prevent it from falling off while running errands.

Earlier in the week, Mary-Kate‘s twin Ashley was spotted getting out of a car and heading into a building in the West Village neighborhood.
