Yes there are Cosplay groups in Sacramento at Evangeline's in Old Sac.
You can cosplay any character! cloud-terra .com has some awesome outfits for cosplay!
Most cons do not impose any restrictions on cosplay players .
As of January 4, 2014, Cosplay does not have any events scheduled in Trinidad and Tobago for 2014.
there are groups for all ages ive seen little kids to people in their 60 - 70 probably older at cosplay events lol
Sadly, and despite the mounting popularity of cosplaying, finding a cosplay "store" is an impossible task. I've only ever seen 2 stores and both very sad. I recommend just looking online. There are a ton of good costumes out there. Look for an American store like cosplay locator.
Well, I happen to think that is a matter of opinion and who ya wanna cosplay as. Most people think it's odd for a guy to cosplay as Italy and it would be odd cosplaying as any of the female characters (as it would be for any anime), but for said male to cosplay as Germany, Prussia, Russia, America or any of the other characters like that then I think it would be perfectly normal (as normal as cosplay can be, that is).
It is basically an interview that describes your cosplay. they have questions that you answer such as , What got you into cosplay? How did you decide on this cosplay? How did you put together this cosplay? Basically a self interview on cosplay.
Choji from Naruto?
It's possible to cosplay anything. As for being able to find the cosplay at a store or something that would depend on the store...but it would be easiest to make one...
Try the cosplay suggestorator..
Anywhere, any time! It's best if you go to Cons though, or cosplay with a group of friends, it makes it more fun.
There aren't any specific "Naruto" cosplay shops. Most carry all different costumes. The best one's happen to be online stores and the best online cosplay store happens to be in the links below :)
