Harry Styles is Dorothy from ‘Wizard of Oz’ at Madison Square Garden Concert

Harry Styles killed — not Freddy Krugger style, but still — Saturday night in NYC, as he chose a throwback both in costume and in song.

Harry performed at a jam-packed Madison Square Garden and hopped on stage as Dorothy from “The Wizard of Oz.” He got it right … right down to the ruby-red slippers. He called the night, “Harryween!”

And, then he sang the staple, “Over the Rainbow,” and it was kinda awesome. Too bad Judy Garland‘s not alive … she could’ve sung “Watermelon Sugar!” Speaking of … does that song work as performed by Dorothy from ‘TWOO?’ We’ll go with YES.

It’s part of Harry’s Love On Tour, and he has one more night at the Garden.
