These are great undies for those of you who may not be a size 5, 7 or 9. I am a size 16 and these undies fit just right! They have a lot of stretch to them, so I think they'd work fine for size 12 and 14 too. They sit just right on the hips and the crotch split is great. I do occasionally get a wedgie, but not too often. There is a heart on the front with rhinestones that bunches the front material together. This heart is held on only by a thin plastic bar that does break over time. Of the 7 pairs of these undies I have, the front hearts have broken off 5 pairs. That's OK with me, though. You can still wear them without the front bunching. They just don't look quite as pretty. But I've found that the rhinestone heart has sharp points to it so even if the heart doesn't break off on you, you might want to take it off yourself because it could scratch your partner -- not what you necessarily want at an intimate moment. I think I might try to go to the fabric store to try to find some other way to do the front bunching without the logistics problems of the rhinestone heart.
Please note that the back is bunched with a rhinestone circle, but I have not had problems with that piece falling off or becoming scratchy. Probably has something to do with where the friction areas are on your body... I highly recommend despite the problems with the front heart. These work really well to cover but yet allow easy access.
