The oldest piece of clothing I still wear (only in the house) is a sweatshirt my son bought for me when he graduated from Cal Berkeley. 1987! No joke. It's quite faded and there are a few holes in the sleeves but it is not remotely indecent. I can open the door to anyone and not be embarrassed. I will never get rid of it. If it gets shredded for some reason and I can no longer wear it I'll put whatever is left of in a drawer. TRUE CONFESSIONS.
