Carey Mulligan [1] showed up to the 93rd Academy Awards ceremony dressed like an Oscar [2] — stunning gold dress and all — but we can't take our eyes off her hairstyle [3]. The updo that Mulligan wore with her strapless ballgown looks simple from the front, but there's a fun twist (literally) in the back.

Celebrity hairstylist Jenny Cho [4] created the masterpiece and documented the entire process from start to finish on her Instagram Story. The first step was curling Mulligan's shoulder-length blonde hair using the GHD Curve 1" Classic Curl Tong [5] (£129). Then, Cho twisted it up to create the twisted bun that we saw on the red carpet. As a finishing touch, Cho used the GHD Platinum+ Professional Performance 1" Styler [6] (£189) to sharpen up the pieces of hair poking out of the style.
