I know so far the KonMari posts have been light on the photos. So here is my first attempt.
These are little cotton knit strappy camisoles I wear under anything sheer or low cut.
I've folded them into squares and they are stored in shoe box sized storage I already had (from Ikea, bought for something else) and in a larger deep drawer (for now at least). Later these may move to the smaller drawer unit which is currently still full of underwear, socks, makeup etc.
