Definitely still have visible panty lines with these. Where most "invisible" panties don't have stitching on the edges, these ones do. It's small stitching and not as noticeable as normal panties, but definitely not something you would want to wear with leggings or a skirt. Otherwise the fit was as expected, but nothing special about these and since i wear leggings or dresses pretty much every day these aren't going to cut it for avoiding visible lines.
