It's a small elastic only at back of the waist. It's meant to cinch the waist in without looking too busy from the front. Similar to the back of this shirt: https://www.lanebryant.com/classic-ls-button-down-w--elastic-b/prd-601238086.html
If there's elastic around the bottom of the top how TF did she come out with it all loose like that?
