You create cosmetic changes to a Simulacrum. You make the simulacrum—including Clothing, armor, Weapons, and equipment—look different. The Simulacrum can be 1 foot shorter or taller, thin, fat, or in between. You cannot change the simulacrum's Creature type (although it can appear as another subtype). Otherwise, the extent of the change is up to you. You could add or obscure a minor feature or make the Simulacrum look like an entirely different person or gender. This does not change any of the simulacrum's abilities.
