i NEED motivation

We went to St George with my side of the family. My little sister wanted to go shopping so I left the boys with Ryan and went with her, my mom, my other sister and her husband. We went to Down East and they had some of the cutest clothes. I found a skirt that I fell in love with and it was on clearance for 10 bucks. I tried it on much to my discouragement it didn't fit. I thought about buying it as a incentive. Maybe I should have but didn't. We went to another store and I found a skirt it fit and its cute I bought it. Here is my issue with that.
It is a elastic band. the other was a zipper. As I've been thinking about it all my comfy clothes are elastic band. I don't look cute and I feel awful I need motivation but I can't seem to find it. BLAH!
