Kate Hudson Has an 'Archive' of Past Red Carpet Looks: They're a 'Piece of My Personal History' (Exclusive)

Kate Hudson isn't one to let a good look go to waste.

In an exclusive conversation with PEOPLE, the actress, 44, says that she has an "archive" where she safely stores outfits she has worn to prestigious events over the years.

"I save them all. I have a very extensive archive at this point," Hudson says. "Not all of them I've gotten to keep over the years, but the ones that I [can], and the ones that are custom and all that, I hold onto them."

"They're also moments in your life, depending on what projects you're working on or what you're promoting, that are really a piece of my personal history," she adds. "So holding onto them is sort of a retrospective of the art that I've created throughout the years, and is really interesting to look back on."

Currently, Hudson says she hasn't gone into her extensive archive to rewear or take out any of her past looks.

"I haven't dipped into them, but when I bring all of those garments out ... it's going to be really amazing to sort of reflect on the things that were happening during that time," she says.

For the mother of three, she adds that the outfits she has worn to prior events — including movie premieres and awards shows — aren't just pieces of attire, but so much more.

"I really see them as art pieces, fashion," explains the Glass Onion: A Knives Out Mystery star. "I really do."

Looking back at past looks she has worn over the years, Hudson tells PEOPLE that she has no fashion regrets.

"You know why? Because I love fashion, and anything that I've ever worn is always coming from a creative place for me," she says.

"I never look back and regret those decisions," Hudson — who recently partnered with the shopping platform Rakuten — continues.

Adds the star: "I think there are things that other people might have thought weren't their favorite, but for me, I've always worn, and choose to wear, what makes me feel good and how I love to express myself."
