The "Watermelon Sugar" singer dressed up in a sparkling Dodgers uniform and sunglasses, similar to the ensemble Elton John wore in 1975 during his performance at Dodgers Stadium in Los Angeles, while attending the 2018 Casamigos Halloween party.
"Now that's what I call a Halloween costume @harrystyles," Elton wrote on Instagram along with photos of Harry in the costume.
Harry and Elton have known each other for years, with Elton even giving the One Direction alum a shout-out during his iTunes Festival show in London in 2013. Harry posted a photo with Elton at the show, calling him a "living legend."
