I used the BIG grannie undies! I didnt have a pad or any dressings on my CS scar after the second day just butterfly tape and I just found that the granny undies wen right up to my belly button and just held everything in and tight and just felt better. Even now I dont like wearing low undies as I find the sit right on my scar and irritate me... so I wear granny undies all the time now! hehehe so attractive!
