Tallulah Willis exchanged vows with musician Justin Acee in Sun Valley, Idaho, on Saturday, wearing a custom Balenciaga couture gown designed by Pierpaolo Piccioli. The strapless silk satin column dress featured a sculptural, curved neckline that paid homage to a similar silhouette Demi Moore wore earlier this year to the Vanity Fair Oscar party.

The gown's design evolved from an initial iteration with a straight neckline, with Willis advocating for a more dynamic shape. "I just thought, wouldn’t it be so beautiful to have no necklace and nothing up here, but just the shape," Willis told British Vogue.

A voluminous draped skirt gathered at the hips, a long train, and a structured bow at the back completed the dress. Piccioli, Balenciaga's creative director, intended the bow to give the impression that the bride was "like a package that was being unwrapped."

The Balenciaga atelier dedicated 712 hours to the creation of the gown, with an additional nine hours for the veil. Each of the individually beaded organza petals reportedly took approximately 60 hours to hand-embroider and apply.

Willis's styling included a floor-length veil, pear-shaped diamond drop earrings, and her hair in a chignon. Her sisters, Rumer and Scout Willis, served as bridesmaids in matching seafoam green strapless dresses.

Willis and Acee announced their engagement in December 2024, following a courtship of approximately two years. The bride described her couture gown as "magical" and "unexpected, kind of like me," referencing her journey toward self-acceptance.

Moore and Willis had previously attended Piccioli's first couture show for Balenciaga in Paris last month, where the designer later met with Willis for a fitting.
