I know all the closet editing wisdom in internet land say to get rid of clothes that don't fit. I change size too often. Not drastically but enough to affect fit. If I eat the wrong food or am premenstrual I go up in size so I don't only change from poor eating choices or doing a cleanse, though I have lost 20 pounds over the last couple of months through cleansing. That is my largest range, 20 pounds but it is enough to affect fit. Mostly I go up & down 5-10 pounds.
So should I keep clothes that are too big?
