Ah yes, the perfect panties, such an important thing! You spend 18 hours a day in these things and you want them to be comfortable. I was a big fan of Cosabella for many years and I still think they are great, but my latest picks are Hanky Pankies
Hanky Pankies are one size fits all, really soft and super stretchy so you hardly feel like you are wearing anything at all. They wash fine as well, I even dry mine! They are currently on sale for $11.90 each at the Nordstrom Anniversary Sale. Save even more if you buy three. Click here to check them out.
