Any virtually alive item (something which is descended from the $body object) can wear things--generally clothing. Anything worn is a Wearable Frob, and must be from the object $wearable_frob or one of its descendants. A new article of clothing can be created by typing:
@new $wearable_frob named Trenchcoat
After it is created you will be holding it. At this point it is worn with the command wear and removed with the command shed. Example:
wear trenchoat
