In a recent interview with Who What Wear, the actress recalled some of her most iconic costumes, including her Buffy wardrobe and all-purple outfit from Scooby-Doo. Gellar revealed that she still has a pair of Buffy's boots in her closet, because she loved them so much. "We used to say, when the boots went on, you know the fighting was going to happen. I still have a pair of those boots in my house that I still fit into," she said. While Gellar admitted that she didn't keep much from her Buffy wardrobe, she did keep the boots, as well as the dress her character wore the first time she was killed and the jacket from the end of the show. Looking back on it, Gellar said she wishes she had kept more from the show, adding, "You don't realize the sentimental importance" of the outfits while you're in the moment.

Telling Who What Wear that those were some of her favorite costumes, she also noted that Daphne's purple boots were custom made just for her. According to Gellar, costume designer Lisa Evans loved a pair of Christian Louboutin boots, but they "did not come in Daphne purple," so instead the costume department crafted a pair "from scratch."

In one scene of the movie, Kathryn wears a sexy corset while trying to seduce Sebastian (Ryan Phillippe). Age 20 at the time, Gellar said that walking into the L.A. shop where the corset was made to get fitted was daunting at first. "I remember the first time [costume designer Denise Wingate] told me we were going there, I got all, like, blushy and shy," she said, adding that she grew more comfortable with it as time wore on.
