What brand designed David Harbour's premiere suit?

David Harbour collaborated with Union Western to create a custom suit for the 'Stranger Things' season four premiere in 2022. The suit featured thematic elements from the show, including characters and the 'upside down' world, adorned with embroidery and rhinestones. Harbour chose this brand because his wife, Lily Allen, had previously worked with them, stating, 'They make these mad suits for rockstars.'
