Baggy pants

Why is it that sometimes the scale won't move much but suddenly it's time for new pants? I should say "trousers" so my British friends don't snicker ;) I might even have to venture in to the two bins of skinny clothes I have and see what's in there! Yesterday's pants could barely zip at the beginning of the summer and when I put them on, I thought they were ripped or something because they would barely stay on. The scale is a constant source of confusion but screw it, I'm feeling pretty good about going down a size or two. Anyone else experience this?

I'm running around like crazy today and tonight working and getting ready for my Scottish family to arrive tomorrow. I'm trying to put together some meals that don't break the money and calorie bank. I'm running out of time! :) Hope everyone is having a great week!
