If you're one of the girls that needed to add more panties to get up to your desired number, then in step 3 you need to buy 2 new pairs of panties each week to build your supply. Both have to be top drawer material.
Also, every other week, you'll have to move 2 pairs of panties from the top drawer to bottom drawer, to make sure you keep an equal number of panties in each. I still want you to throw out a bottom-drawer pair every week, how else are we going to get rid of the least-sexy panties in your collection?
