local fighters = game.Workspace.Teams.Fighters
local defenders = game.Workspace.Teams.Defenders
plr = game.Workspace.LocalPlayer

	fighters.Shirt.ShirtTemplate = "http://www.roblox.com/Red-item?id=157673817"
	fighters.Pants.PantsTemplate = "http://www.roblox.com/Pants-item?id=157684158"
	if plr.fighters == true then
		plr.fighters.Shirt.ShirtTemplate:Destroy()
		plr.fighters.Pants.PantsTemplate:Destroy()
		wait(3)

	end
end
