Well, two of them, really.
1) After I've worn them for a bit (ie, not right out of the dryer), I can pull my jeans completely down while buttoned and zipped. I want to run out and buy new jeans, but I'm going to hold off and make sure I really will fit into a 14.
2) When I was getting dressed this morning, I noticed my bra didn't fit quite like it used to- there was a gap in the cup right by my armpit. I moved the clasp over to the center loops (instead of on the loosest loops), and it fits! YAY!
