Presets allow you to save several of your favorite customisations for each Neopet! Using presets allows you to go back to a favorite outfit after you have changed it to let your pet show their Altador Cup team spirit or dress up in their newest items.
Remember that items saved in "presets" will be marked as "worn" by that Neopet and will not be able to be worn by any other pet until it is removed from the "preset" option.
