Tomorrow is Hallowe'en. I bought Spock ears and a pin that looks like the Star Trek communicator to wear to work (it's apparently I thing, and I'll be darned if I was going to do something as boring as cat-ears). The ears are a bit bent and cheap and won't really sit well, though, so I think I'm just going to wear the pin.
Paired with black dress pants and a v-neck golden long-sleeved tee. You know, to make sure people get the point.
This is the closest I've ever come, and probably the closest I ever will, to cosplay.
