I'll be wearing one on Saturday for a Halloween LEGO event, and then I'll need two costumes for BrickFair public hours next week.
I've got three options: Eleventh Doctor, Indiana Jones, and Jayne Cobb. Jayne works best for Saturday because I know I'll be more comfortable in a t-shirt. It works best overall because I have a trimmed/maintained beard, but I'll ignore that feature for the other two. But the Eleventh is also easy because I can forgo the tweed jacket if bodyheat/internal temperature rises. But Indiana Jones is fun too, though I no longer have the whip. So I feel like the Doctor and Jayne costumes are more favorable for the events. Beard and all.
Still, it's a tough choice. What do I want to cosplay right now?
