For Halloween in 2018, Styles dressed as one of his favourite musicians — Elton John! John wore a bedazzled jumpsuit when he headlined Dodgers Stadium in 1975, and Taron Egerton wore a similar suit when he portrayed John in 2019's "Rocketman." If you can't score your own bedazzled Dodgers top online, you can glue sequins to a regular one yourself. A Dodgers hat and Elton John sunglasses complete the costume.
