Jewel Wears Second Show-Stopping Gown at Her Art Exhibit Preview — See the Ethereal Look

The singer donned two dresses that looked like works of art at the preview of her exhibition, The Portal: An Art Experience by Jewel, on May 3

Jewel is a work of art.

The singer and artist, 49, turned heads in two show-stopping dresses at the preview of her new exhibit, The Portal: An Art Experience by Jewel, at the Crystal Bridges Museum of American Art in Bentonville, Ark., on Friday, May 3.

The "Foolish Games" singer donned the second dress for dinner while performing "Over the Rainbow" on stage and then hosting an auction of four of her guitars, two customs songs and a mini sculpture she created for $1.25 million, which benefitted the museum.

Jewel wore a simple off-white L’Agence silk slip dress with an ethereal piece of moving artwork attached to her back like wings. At times, the feathery structures appeared to look like flowers but morphed into shapes that resembled butterflies. The singer complemented the stunning look with a pair of white Stella McCartney boots with a chunky nude heel.

The piece was designed by Casey Curran, who posted a video on Instagram showing how the wearable art moved. "I'm so thrilled to finally share this piece worn by the unbreakable and ever illustrious @jewel for her stellar exhibition The Portal @crystalbridgesmuseum," Curran captioned his post.

Jewel's first gown of the evening was created by Iris van Herpen and included an intricately sculpted silver design over a nude slip. She wore her hair in a simple, loose updo and kept her makeup minimal and natural.

“I am a fan of this artists work — both wearable work and not wearable — because of my use of traditional mediums as well as new tech," says Jewel exclusively to PEOPLE. "I wanted both outfits to evoke the intersection of technology and art and designers Iris van Herpen and Casey both represent this. I reached out to Casey on IG and he was kind enough to make this piece for me."

The artist told PEOPLE that the theme of the night was "the unseen realm." Both of her looks embodied that theme.

“It revolves around an idea that we all travel through three realms of reality every day, often without realizing it,” the "Standing Still" singer explained. “Our inner realm, which is thoughts and feelings, the physical world and then the unseen, whatever that means to you."
