What does crossdressing have to do with Norse mythology? EVERYTHING. The Vikings were odd people (and if you don’t believe me just look up the story about Loki and the goats). But, I digress.
So, who is our next crossdresser? Thor, God of Thunder of course! One day in the wonderful planet-y place of Asgard he loses his dear hammer Mjolnir to the eeeeeeevil giant Prymr. The eeeeeevil giant demands the beautiful Feyja in exchange for Mjolnir, but Freyja ain’t havin’ none of that. So Loki comes up with a glorious plan as usual (see goat story):
HE DRESSES THOR UP AS A WOMAN.
So Thor pretends to be Freyja dressed in a bridal gown (I think it was either mermaid or ball gown style, I’ll have to double check), some shit goes down, and in the end Thor goes frolicking in the meadow with Mjolnir, which he safely retrieves from Prymr.
Meanwhile, Loki is laughing and wondering why the gods do everything he suggests.
