Skeleton horse
Hands down, this must be the best costume we’ve seen yet. We have some close competitors (we especially liked the Harry Potter ones, the Elvis costume and the Minion), but this makeup is too impressive to ignore. Whoever painted this horse must be a professional makeup artist, or else they spent hours in front of makeup tutorials.

The horse looks like he’s been taken out of a horror-fantasy movie set where he plays the part of a ghost-skeleton horse who’s back from the dead. This horse’s costume reminds us of the night riders in Lord of the Rings, or any other spooky character riding a horse and looking for lost souls. It seems like taking off this paint might take a while and more than a couple of showers, but the best costumes often require making sacrifices.
