Knix made me like undies. I was tired of uncomfortable underwear that rode up, flipped down, too tight in some areas and too loose in others. I was tired of undies that started to break down after a few washes. They are so worth the cost in the long run, they fit so well, don’t ride up or flip down, I’ve had them almost 1 year, wash them in the laundry with everything else and they still look new. They’re soft and silky and hardly feel like I’m wearing anything at all- and they are true to size (I’m 5’ 0” aprox 145 lbs and wear a size 10-12 and got a large) I have not tried the bras yet
