I love Just My Size panties. They are soft and they don't ride up. I have a good size bottom and they stay in place.
I'm not sure if it's the product or the sizing, but this is not what I expected. I followed the size guidelines, and have to admit that then I opened the package, I was stunned by the size. I thought, "Well, I've opened them, there's no going back" - and threw them in the wash. The first hour or so is great - they actually do fit and are comfortable. However, as the day wears on, and the cotton stretches, the comfort goes right out the window. By the end of the day, the leg holes have almost no integrity, and they are sagging, and twisting. If it wasn't for the waist elastic (which starts at my waist, and then rides up to my ribs) they'd fall right off. I've also noticed that the print version have less overall shape or shape holding. I'm disappointed. Not a fan of briefs to begin with, and this certainly has cemented their place in my "ugh, only if I have to" pantheon.
They looked huge when I first took them out of the package. Due to the smell, gave them a quick wash in cold water and dried them on delicate in the dryer. Panties shrunk at least two inches round.
Really great cotton undies. I love and work on a farm and they are comfortable summer and winter, really last and get softer as you wash them more.
