Channeling her inner Alice, the “Calm Down” singer sported a pair of Sezane Paula Babies heels in an “Ecru/Black” colorway. Retailing for $215, the footwear pick featured a strappy slingback construction fixed with antique gold adjustable buckle closures. The shoe was paired with white ankle-length socks from Bombas fixed with a lettuce trim.

In the snapshots, the Rare Beauty founder, 32, appears in a blonde wig and light blue dress as Alice and the music producer and songwriter, 36, is decked out in full makeup as Johnny Depp’s Mad Hatter from Tim Burton’s 2010 movie adaptation of the book.

Whether recreating their own notable roles or paying homage to iconic films, stars this year offered a variety of creative and fun looks.
