Granny panties

I've heard from a couple of different women who have had c-sections that I need to buy "granny panties" so the elastic doesn't touch my incision point. When I was at Target today, I was searching for under-roos that fit the bill and think I've found some when a woman in her 80s walks over to the exact same rack and grabs a pair. Thank you, granny, for confirming I was looking at the right pair!
