I agree on what ashley said regarding memory usage but you should still destroy non-used objects on the layout on startup on negative(-) coordinates since many objects present on the layout (even invisible) still affects fps and cpu usage. I recommend preload images on startup by putting all sprites(images) or tiledbackgrounds(images) that are going to be used on you layout on the outside part of the layout and destroy on startup , create to insert the outfit & destroy to remove the outfit.
