Retired clothing (or "rare" clothing) is a group of clothing items in MovieStarPlanet that are no longer obtainable by regular means. These items were all once sold in the shop but have since been removed.
MovieStarPlanet has never stated their reasons for removing said items, but many players suspect that these items were removed due to issues with covering and fitting the avatars, copyright, being inappropriate, and/or being outdated.
The "Geometric Skirt" was previously a retired item; however, it was added back into shops not long after its removal. It's believed that it was added back because of the response from the community.
Several retired items returned in rare week themes during fall of 2013, 2014, 2015, and 2016 as well as spring of 2016 and 2017.
During the 2015 rare week, some items not included in the theme were available for various lengths of time due to bugs.
The 2014 theme "I Love Paris" added the "Nerds" glasses back into stores with an increased price.
In the 2014 shop update, many items were returned to stores.
