Wardrobe Wizard can fit clothing to custom character morphs. I ran a test with one of my character morphs and a polo shirt earlier this month. Step 1: Load the default unmorphed Stephanie Petite into the scene, along with a given clothing item, and let Wardrobe Wizard perform its analysis on the item. Step 2: Replace the default Steph with Irina, then convert the clothing to the morphed figure.
