Yes! New panties make a world of difference! There is nothing worse then feeling your underwear creep up on you, unless it is feeling them fall down around your knees!
I got some for my birthday! I'm so glad I did. I bought 4 packages, they were on sale. I left 2 of them sealed, so if I need a smaller size later on...no problem! They are in a drawer in the bag with the receipt! So if I shrink enough, I can easily exchange them!
Undies that fit are like having shoes that fit properly. If 1 or both of those 2 don't fit, you're not going to have a comfortable day at work or out running errands.

Yippee for proper fitting panties & footwear!
