I often try justify the purchase of a light or see through-ish item with the thought “Oh, I can wear it to the beach!” despite the fact that I go to the beach at most twice a summer. For my mother, the justification is “Oh, I can wear it to sleep!”. Seems like a good excuse to purchase yet another loose and soft item, but seriously, how many sleep outfits do you really need, mom?
But now, I have a better one, “Oh, I can wear it to go shopping on weekends!”. Much more practical and includes pretty much everything I would want.
