Perfectly thin. Just what i needed. The lace stretches a little but it doesn't cut off your circulation either though. You can pull it up where it gets stuck.  Its movable.  Im a 14/16 and the xl fit great.  I think i read someone say these were too thin well Yea the title-- description says so. ULTRA THIN. They're meant to be WORN UNDER THINGS not as pants.  These are perfect for these cute 2 piece sets and boho flair bell bottom type pants that are trending these days but are so terribly see through. Ugh! Also great for wear under thin flowy skirts and dresses.  As you can see from my pics you can see my fingers through it so if you order you'll know what you're getting.
