I currently have one pair of size 6 jeans:
Right now, they don't fit. I mean, they DO fit in that they zip up and button, but they DON'T fit in that the end result is that which causes fear and horror among women across the country: The Muffin Top.
Which of course is completely unacceptable.
I'm running another half marathon in November. By that date, these jeans are going to fit proper.
