halloween costumes for queer couples

I think you have found a problem that a lot of us come up against. Costumes, cards, hetronormativity is  everywhere! I love your creativity with Bert and Earnie. The way I personally do costumes is what I am into at the time, and who cares what gender it is suposed to be for. If you want costumes of the correct gender you could look at lists of LGBT films and TV shows. In the end it's should be whatever makes you comfortable and whatever you enjoy. I LOVE dressing up, we don't get to do it enough. So have fun. Looking at THIS list Santa and an Elf is excellent. 

All the best
