I don't carry a J-Frame IWB. To me the gun is designed to go in a Pocket or on the Ankle.
If you absolutely "must" go IWB with a J-Frame I would look at carrying in the "Appendix" Position. Mitch Rosen makes one called the "Workman" that is good for deep concealment, no jacket needed. It's a "Tuckable".
