Well, they are usually exhibited at game or comic cons, which are held in many different countries quite often. There's usually 3 or 4 per year per country, depending on Companies and releases, so there's a lot of opportunity for people to exhibit their costumes.

I doubt I'll ever come across one in my current years.

I would love to attend one, but they are sadly not to common in my area or really that frequent in my country. More pics:
Oichi


The Qiao's, Zhen Ji and Zhou Yu



Zhuge Liang




All awesome. I'm not so keen on the Zhen Ji though, I mean way better than i could do, but I've seen a lot more accurate cosplays. The Zhuge Liang has amazing detail.

Oichis Toy is hilariously small.


I wouldn't of known that was Zhen Ji unless you told me.

It took me a while to regognise the outfit, after looking for a while i can see the outfit she was trying to pull off, it just didn't go well. Length and lack of acsessories make it hard to recognise. The others in the photo are good though.
