This here is a page about costumes you can make for free on poptropica. This is just my way, but beleive me when I say that there could be many, many others, including your own!
*The Hunger Games*
Katniss Everdeen - Tribute Outfit I made this costume by finding people with the right clothes. For the hair, I'd go with dark brown, and for the eyes, they should be showing the eyelids. The mouth should most likely be a frown, and for the clothes, just find random people with brown pants, a black shirt, and a black jacket. If you could find someone with a brown or orange pack, that would be an awesome extra. So would the bow and arrows from Vampire Curse Island, if you can find that.

Katniss Everdeen - Hunting Outfit I made this just about the same as above. The only difference is that you shouldn't use a pack, and the clothes should be a little different. You need a brown jacket, a black shirt, and brown or black pants. The bow and arrow is also good for this.

Peeta Mellark - Tribute Outfit I would say basically, just put this as the Katniss tribute outfit, but without the bow. Different color/style of hair, too. (The above picture was taken by ShirtDogNintendo)
Primrose Everdeen I, personally, would use just about any clothes. I'm not completely sure of the popular Prim outfits, so... Mainly I would do this (the above). Any clothes will do, this is simply what I chose. (The above pictures were taken by me, off-account, and by PrimroseOfHungerClan)
