You can buy cheap outfits at Amazon and at Wallmart.
You can't buy the entire outfits or horns from anywhere.

There should be a cosplay store in the United States, but if worst comes to worst you can just buy cosplay online.
If you need a cosplay fast and cheap the best place to always go is the thrift store that's where I have gotten all of my cosplay. (And I cosplay S. Italy)
You can cosplay any character! cloud-terra .com has some awesome outfits for cosplay!
That all depends on who is making them, and what the character wears. However, I always recommend making cosplay outfits out of materials that you would use for every day clothes. Avoid using materials like overly shiny and cheap costume satin. If you make your cosplay as you would if you were to wear it every day, it will end up looking more realistic, and less costumy.
There are a number places to purchase cosplay costume and most of them are online. Here's a list of some of them:AmazoneBayCosplay MagicMoon CostumesYesAsiaCDJapanCosplay StationCosplay Locator
Cosplay is never entirely cheap, unfortunately. But, I have seen many available on both Amazon and Ebay.
You can wear anything you'd like. If you can't buy a Cosplay costume make your own costume with whatever you have and try to make it look similar to a Anime TV show you like.
