Frankenstein and his Bride. A classic couples costume.
Fred Astaire and Ginger Rogers. The couples costume of the movie buffs
Mary Poppins and Bert. Pretty sure this look exists in Brooklyn
For the group costumes I couldn't get enough of these...
Trolls. A group costume for anyone of the 90's childhood and earlier.
Army Men. Classic group costume.
And for good measure...any group costume from the below would be majorly rad!
