* Transforming your look: Implies a more drastic change.

* Reinventing yourself: Suggests a more intentional and significant change in personal style and image.

* Experimenting with fashion: If you are trying out new styles or trends.

* Changing your wardrobe: Focuses on the clothes themselves.

* Cosplaying: If you are dressing up as a specific character.

* Cross-dressing: Dressing in clothing typically associated with the opposite gender.

* Transvestism: Sometimes used interchangeably with cross-dressing, but can also have specific psychological meanings.

The most appropriate term depends on the specific situation and the intention behind the change in clothing.
