I find the fact that you are all wearing armour alongside modern day footwear pretty funny.
I told them to take the pictures from the knee up, but one listened to me! :-P
We do actually have period clothing, and if I were doing a demo for outsiders, I'd definately put them on. When we train in class, its at a modern fencing school, and everyone wears athletic clothing for normal training. Since that's what we're already wearing (I'd been teaching for about 5 hours before I put on the armour), we just threw the armour on top of our clothing rather than changing.
