                    v:remove()

            end
        end
        if character then 
            for i,v in pairs(character:GetChildren()) do
                if v:IsA("Hat") then
                    v:remove()
                end
            end
        end
        local Shirt = Instance.new("Shirt", character)
        Shirt.Name = "DefaultS"
        Shirt.ShirtTemplate = "https://www.roblox.com/Kestrel-Grey-Polo-item?id=188448874"  
        local Pants = Instance.new("Pants", character)
        Pants.Name = "DefaultP" 
        Pants.PantsTemplate = "https://www.roblox.com/Kestrel-Black-Textured-Pants-Bottom-item?id=220200871"                    
    end)
end)

What it is suppose to do is 1.Delete Character Hats,Shirt,Pants 2.make new pants and shirt 3.put the New pants and shirts in the character

everything in that list works but the thing is they shirts and pants don't even show up on the character! there no errors in output it like the character clothes are invisible
