I'm 5 years from my last c section and I have no issues with my scar. I wear bikini, thong, boy shorts etc. It actually looks like it's not even there. I've had 3 c sections by the same obgyn and she did a wonderful job.

Under the belly maternity underwear.

I’m almost 4 years PP and I still wear granny panties. I don’t like anything sitting in my scar.

To be honest low wearing thongs feel most comfortable for me. High granny style underwear rolls up under my belly RIGHT at the spot where my scar is and puts more pressure on it.

I am 5 months pp. I use h&m maternity undies. Basically granny panties. I can use my old undies with lace (I use the ones that was cottpon and has a lace ege seen on, so it has a seam exactly where my incisions is) etc also. But not two days in a row. 😃 They still make thw incisions site itch in longer use a bit, so I avoid overuseing them. So now when I buy new ones I just have to look more at the front, but as I don't need to buy all new yet I am replaceing gradually and I just buy from a store where I can look and touch them before buying.
