I have seen the inner wear referred by you. Infact, my stoma nurse had given me one. Unfortunately, that was meant for girls. The undy was from one of the UK companies and was costing about 120 USD. My stoma nurse told me that it should help, but I can't comment since I could not use it. I am using the normal abdominal binders for incisional hernia for the last three years.
