If using a parametric avatar, switching between different poses can help highlight fit issues that may not be apparent in the base pose. Dynamic poses relevant to the anticipated final use of the garment may help with creating the right fit.
To change poses:
In the 3D window, click the pose name. The available poses are displayed.
Click the desired pose. Allow the avatar to move into the new position and for the simulation to finish.
View the garment in the new pose.
