For the flatpacked version, see Oak fancy dress box (flatpack).

The Oak fancy dress box (also known as Oak costume box) is a piece of furniture that can be built in the Costume room of a player-owned house with the Construction skill. Costume boxes are used to store costumes or fancy dresses from random events.

The oak costume box is used to store 2 types of costumes. Building this costume box requires at least 44 Construction and 2 oak planks.

Costume boxes can be flatpacked, and bought from the Grand Exchange. Building a flatpacked costume box does not require the actual Construction level.
