With the clothing mesh parented to an armature, you can now perform quick tests to verify that your t-shirt deforms correctly.
To test your t-shirt's movement:
With your armature active, navigate to the Properties Editor > Armature Properties tab.
In Viewport Display > Show, enable In Front. The In Front property enables you to easily see and access the bones for posing.

Switch to Pose mode, then click on various bones and press R to rotate and set a pose. After pressing R:
- Click to save the rotation.
- Right-click to cancel an unsaved rotation.
- If you have saved a rotation, reset your pose in the viewport with right-click and select Clear User Transforms.
Try various natural poses of your character to ensure that your clothing stretches and fits correctly. When you are done, do not delete the armature as it is a vital component for your t-shirt to layer correctly in Studio.
