What's missing here so that npc always checks if you have an outfit before selling the addons. If not, he refused to sell.

if the code is for tfs1.2 you should update almost all those functions but yee, you can use this.

Lua: 
        if (player:hasOutfit(addoninfo.outfit_male) or player:hasOutfit(addoninfo.outfit_female)) then
            if(getPlayerMoney(cid) >= addoninfo.cost) and (items_number == table.maxn(addoninfo.items)) then
                doPlayerRemoveMoney(cid, addoninfo.cost)
                if table.maxn(addoninfo.items) > 0 then
                    for i = 1, table.maxn(addoninfo.items) do
                        local item = addoninfo.items[i]
                        doPlayerRemoveItem(cid,item[1],item[2])
                    end
                end
                doPlayerAddOutfit(cid, addoninfo.outfit_male, addoninfo.addon)
                doPlayerAddOutfit(cid, addoninfo.outfit_female, addoninfo.addon)
                setPlayerStorageValue(cid,addoninfo.storageID,1)
                npcHandler:say('Here you are.', cid)
            else
                npcHandler:say('You do not have needed items or cash!', cid)
            end
        else
            npcHandler:say('You need to have the outfit first!', cid)
        end
