So, I start seing a lot of the things I wish I didn't have to see every day.
First: Día de muertos (yeah, I know you think it's called Día de los muertos, but no) is not your costume theme.
I know a lot of people rant about how you shouldn't paint your face as a sugar skull, and well… I agree. It's a lovely make-up, of course, it's cute and fun to do. But sugar skulls are part of our traditions, they are used to represent our dearly departed.
If you want to use a Mexican theme costume, go for La Catrina! Why? Because she's an elegant skeleton. You can go all kinds of crazy with a Catrina (or Catrín) costume. She was created by José Guadalupe Posada as a critic to the Mexican who tried to act and look like European bourgeois, he called her La Calavera Garbancera. Later on, Diego Rivera portrayed her in his Sueño de una tarde dominical en la Alameda Central mural and he was the one to name her Catrina.
Second: If I see any more Frida Kahlo fan art with Día de muertos elements… I'll puke! STOP THAT! No, really. Stop.
Frida Kahlo was Mexican and I'm sure she enjoyed the Día de muertos festivities but… that's it. Her art and her life had nothing to do with Día de muertos. And the only real relation between her and Día de muertos is that nowadays the museums were you can find hers and Diego Rivera's art make beautiful ofrendas and other events on those days.
Oh, and third:
The Día de muertos celebration meaning is not something like: "Yay! They are all dead!". Is: "Let's prepare a party because our dearly departed will come and visit us during those days. Let's prepare everything to welcome them and treat them with all the things they liked when they were alive".
If you have any doubts, feel free to write me!
