Fear not, it is a girl thing, very normal for our girl wardrobes to grow in size weekly.
My male wardrobe has been stable for years and fits into two small dresser drawers, and I own two pairs of male shoes.
Our children are adults and out on their own, so my wife and I have the house to ourselves, two girls living in the same home, so much fun, girly stuff all over.
Weekly sales bring new clothes into the home, along with trips to Goodwill. Then, periodically, we have to conduct thinning out operations and donate stuff to Goodwill or homeless shelters.
So much fun being a girl!
