I used bellefit. They make one specifically for csections. It was amazing. I felt normal. I used it right after birth
I just ordered mine from Shrinx.com. They also have a panty specifically for csection support & they're reasonably priced. I got the belly band & hip band.
Get a belly band they work wonders for after a c section and after mine I used it every daybit helped with the pain and also helped tone down my tummy. It may or may not work for you but try it:)
