I’m looking for a good Halloween costume idea for either a couple or 2 couples. Could possibly be based on looks vaguely. First couple is a blond girl and a brunette guy and the second couple is a redhead guy and a brunette girl. All of us are average height.

If you think of anything for two people, first couple only that would be fine. Just trying to get some ideas so we’re ready a couple months from now. Thanks
An example of a costume that we used last year was the characters from Archie’s comics.
