Impersonations

I don't really know what to call this one either so...

Mirabel and Camilo both pretend to be each other, even without his gift of shapeshifting.

Pepa, Bruno, and Julieta swap clothes with each other every so often just because they think it's fun.

Isabela and Dolores occasionally switch outfits and hair styles, though they did it more when they were younger, before Isabela was promised to Mariano. After the movie, they went back to swapping. 

Isabela and Mirabel used to purposefully mock the other one, Isabela would make vine glasses and make fun of her sister in her impersonation, and Mirabel would douse herself in flowers she found and make fun of Isa.

They still do this post movie but now it's a much nicer way, kind of like how Mirabel and Camilo or Isabela and Dolores do it.
