Choji from Naruto?
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).
You can cosplay any character! cloud-terra .com has some awesome outfits for cosplay!
Yes there are Cosplay groups in Sacramento at Evangeline's in Old Sac.
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.
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...
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 :)
The same place people get any ideas. From their imaginations!

You can be any size to skate.
There are no cosplay stores in Utah. However, some Asian import stores do sometimes have a small costuming area with props and/or wigs. However, cosplay communities online will advertise cosplay yardsales, or swap-meets.
