Losing weight can be a doubled edged sword. Most of the pants I own no longer fit - a happy problem, I suppose. It was necessary to purge my closet of clothes, too big, outdated, worn out...to make room for new things I recently bought. (I still need to go through my ironing pile. Hopefully, some of those things can be tossed too!)
After sorting, buttons and clothing labels were removed from items no longer good enough to pass onto the thrift store.
