Girllll, if you don't own a pair of these type of panties then you are missing out in life lol
They are seamless (very thin). Crotch area is 100% cotton. Super comfortable. I love these types of panties! Need to have a pair for backup for a outfit/dress, because girl those moments will come and when you pull one of these out you already know you going to be feeling comfortable the rest of the day/night!
