# Upgrade Costume

<figure><img src="/files/DN5i8z18C0Nwolsh7lDl" alt=""><figcaption></figcaption></figure>

Each costume can be upgraded up to +5 using its costume design.&#x20;

Each time a costume is upgraded, skill stats are enhanced, cool-down times are reduced, and SP requirements decrease.

If you already have a costume and obtain the same costume by drawing or from rewards, you will obtain the design for the costume instead. If a costume cannot be upgraded further and you obtain the same costume, you will receive a Golden Thread instead of a costume design.
