Kate Bosworth was glowing last night at the Solomon R. Guggenheim Museum in New York City, during a star-studded party announcing the winner of the Hugo Boss Prize 2014. The actress, dressed in a strapless Boss dress, Kurt Geiger pumps, and Harry Winston diamond jewels for the event, joined other famous faces including Margot Robbie, Nicola Peltz, Joshua Jackson, and Scott Eastwood. While Bosworth stunned in her ensemble, it was another important look she's worn that was on her mind: her wedding dress, designed by the late Oscar de la Renta.

"When it came to my wedding gown, Oscar said, 'I hope you feels as beautiful in the dress as you do with her husband.' I thought that was such a great thing to think about as a bride," Bosworth shares. "Of course you want to feel beautiful in what you’re wearing, but it’s really the person the person that you’re marrying that’s going to fill you with that kind of joy and love everyday." And it seems as if Bosworth's husband, Michael Polish, certainly does. "We make each other laugh a lot. We have a lot of fun," she says. "Our ideal date night would probably have to involve a bottle of whiskey."

The actress revealed that the dress is now stored for safe-keeping: "It’s archived! He made me two, so I took it to a couture archivist and had them do a very intense process of kind of going through every thread. Oscar just knew how to make a woman feel so beautiful, and I want to preserve that."

But de la Renta isn't the only designer the actress admires—she also had amazing things to say about Jason Wu (her date for the event) who designs the Boss womenswear line. "I’m such a fan of Jason, he’s such a fun person," Bosworth says. "Just having a hem pinned by Jason is such an experience! He takes his time, he’s such a perfectionist. He loves what he does so much and just sees lines in a specific way. You can look at a piece and think 'Oh, maybe that needs to be a little bit shorter,' but he gets right to it and it changes your perspective. He’s that good."
