It's Chanel-oween for Fergie and Josh Duhamel

Scream Queens may have coined the term Chanel-oween but some other folks are really running with that idea.

On Friday, Josh Duhamel went to a party dressed as the iconic fashion label's boss, Karl Lagerfeld. 

Wife Fergie suited up as his cat, Choupette. (Nice touch!)

And then there are the Royal Twins, a pair of girls with their own Instagram account and, we assume, some seriously fashion-obsessed folks

Here they are chanel-ing Coco and Karl

And the label's famous quilted bag
