No, Vicky 4 works with a special facility called Magnetize Poses to fit clothing to her. You can find all the relevant details in the V4 readme, but briefly,

1. Load V4
2. Load clothing item
3. Conform item, and make sure the item is selected
4. Go to Pose library>DAZ'S Victoria 4>Magnetize Clothing and choose the first pose, called "!Magnetize to V4".
   (The other poses, 1, 2, 3 etc in that folder are for if you have multiple V4 models in one scene.)

Try it and see... most clothing will work much better if it's built with JCMs, which this item is, judging by the description.
