Probably spiked leather collars. Not THAT unusual. I do have a real nice heavy one, about 1.5'' wide, two rows of 2'' tapered steel spikes. Its really comfy, autie thing probably, I like the compression.
And a tiny, tiny leather jacket, really tight fitting. Again, same thing. Cost me about £12 in a charity store, I always check them every time I go into town, just in case anyone has donated them any nice leather jackets.
Got a nice biker style jacket that way, and a full length leather trench at a knockdown price. Can't remember how much but it was fucking cheap as.
