Old lady
This costume is so realistic, you probably don’t recognize the woman behind the makeup. We’ll give you a hint: she’s an international supermodel. Don’t beat yourself if you still can’t figure it out, since this costume is just too good. This is supermodel Heidi Klum wearing old-lady makeup and clothes.

We didn’t include celebrities on this list, since, in a way, they have an unfair advantage, but we had to include this costume since it was just too good to ignore. Heidi Klum is known among her friends and colleagues as the queen of Halloween, since every year she masters the holiday with yet another incredibly realistic costume.
