Mannequin Try On feature problem?

I'm encountering some problems with a TryOn function that I'm using in my mannequin system. The main issue is that after the remote used for trying on clothing gets called once it sort off breaks and whenever I try to try on other clothing It equips the player with both the Shirt and the Pants of the mannequin instead of only one of them-- in my debug script it prints both Shirt and Pants instead of only one of them. Here's the main function:

local function TryOn(p, player, ClothingId, Action)
    if Action == "Wear" then
        print("ACTION: wear clothing.")

        local ClothingType = MarketplaceService:GetProductInfo(ClothingId).AssetTypeId

        --- 11 is the AssetType Id for Shirts
        --- 12 is the AssetType Id for Pants
        if ClothingType == 11 or Enum.AssetType.Shirt then
            print("Shirt") --/ equip player shirt, print function for debugging
        elseif ClothingType == 12 or Enum.AssetType.Pants then
            print("Pants") --/ equip player pants, print function for debugging
        end
    elseif Action == "Reset" then
        print("ACTION: reset.")
        player.Character.Shirt.ShirtTemplate = player:FindFirstChild("originalShirt").Value
        player.Character.Pants.PantsTemplate = player:FindFirstChild("originalPants").Value
    end
end
