I've been wearing these under dresses the last few months (because I hate pantyhose) and so far I believe they're fairly satisfactory.

Pros:
- Nice double crotch panel that goes across from the bottom of one let to the bottom of the other.
- Reasonably heavy fabric, not flimsy at all (I launder regularly with no chlorine bleach then hang to dry)
- Nicely hemmed.

Cons:
- The fit felt a little small for the size I ordered
- They do ride up slightly after I've been sitting and squirming for an hour (due to health problems I can't sit in one position for more than about five minutes so I shift a lot when I have to sit)
