    Adore

    J'adore. Couvre le ventre, j'ai essayé une taille plus petite cette fois ci et c'est aussi un bon fit pour un ajustement plus serré. Le tissu est assez extensible

    These are all I wear. My bladder is a bit weak post cancer and these are a godsend.

    This is my third brand of period panty and while all are good, these are by far the most comfortable and most absorbent of the the 3 brands i own.

    Love the fit

    Although I normally wear "medium", I've found that the Knix underwear stretches so with the small it's a better fit with no droopiness. I now wear Knix underwear exclusively, quite a switch from "Hanky Panky"!
