Old Lady
This costume is so realistic that you probably wouldn't recognize the woman behind the makeup. Here's a hint: she's an international supermodel. Don't worry if you can't figure it out; this costume is too good. It's supermodel Heidi Klum in old-lady makeup and attire.
We typically don't include celebrities on this list because they have somewhat of an unfair advantage. Still, we had to make an exception for this costume because it was too impressive to overlook. Heidi Klum is renowned among her friends and colleagues as the queen of Halloween, as she consistently stuns with incredibly realistic costumes year after year.
