    Love These

    Honestly, I love the fit of these. Given the changes in my body shape (thanks menopause belly) I no longer love my bikini fit and was struggling to find anything comfortable in the Knix range. Enter the french cut! This is what I've been waiting for. Higher fit, more coverage, covering my lower belly resulting in a much cleaner line for my clothing and even more important, so much more comfortable. I feel better in this style and they are much more flattering too.

    They changed the sizing with no warning. Order the next size up

    Very disappointed with the change. I am a long tome knix wearer. Primarily for comfort. I cant think of much worse than someone shrinking your underwear. I have notified them Going to try the next size.

    Ordinarily I would give the highest rating.
