What the Heck???

I was just struggling through my ever sparse closet trying to find something cute and professional to wear to work tomorrow. I tried on a few of my size 12 skirts I had bought a few weeks back. They are already starting to get too big! What the heck??? I am now thinking I can wear them for another four-six weeks tops. Darn I even think I might be able to soon wear a size 10 skirt? WOW! WOW! WOW!
