Harriet Slater Wore Siobhan Mackenzie To The ‘Outlander: Blood Of My Blood’ LA Premiere

Harriet Slater attended the LA premiere of Outlander: Blood Of My Blood at the DGA Theater Complex on Monday, and while the British actress isn’t Scottish herself, her look gave a respectful nod to the Highland roots of her character, Ellen MacKenzie—who hails from the storied Clan MacKenzie.

This detail felt especially significant when taking in her look: a dramatic purple, navy, and green tartan maxi skirt designed by Scottish designer Siobhan Mackenzie, whose work is deeply connected to her own Scottish heritage. With brands like Burberry, Dior, and Ralph Lauren all recently embracing tartan in their Fall 2025 and Resort 2025 collections, Harriet’s decision to wear a designer rooted in the Highlands added authenticity to the theme.

The look was styled with a sheer black Zhivago bodysuit featuring sharp padded shoulders and a Pritch leather corset belt, giving the outfit structure and edge. Completing the moment, her jewellery came courtesy of Laings of Glasgow—a final, sparkling tribute to her character’s Scottish lineage.

Stylist: Harriet Nicolson.
