Yes, that is a red jumper. Yes, it is teamed with red pants. And yes, the look is finished with red shoes.
But wait, there's more.
Unfortunately you can't see it that well here as I had to be as inconspicuous as possible, BUT...yes, his hands and face are painted red. Actually, his entire head was painted red (he had a buzz cut).
Maybe he likes red. A LOT.
I have nothing left to say on this.
