Last year bf's sister gave me a bunch of her old jeans that she no longer wore, or that were too small for her. She figured most of them would fit me since hips are smaller than hers, but at the time she gave them to me, they did not fit. The pant sizes were mostly 14/15 some "petite" some "medium". She was shocked that they didn't fit me, but I told her I would take them anyway as a "visual goal" as I worked to get out of pregnancy pants. A few months ago (I think in February actually) I broke out of pregnancy pants, but just barely. The pants I wore in February were 16's and they fit, but were snug.
Today...those size 16's are much more comfortable, and I noticed they were loose in the areas they once were snug. Curious I went to closet and found a couple pairs of the "medium" sized 14/15 pants bf's sister had given me. And they fit, like a glove. When she initially gave them to me, I was lucky if I could get them up to hips let alone button them up. Today, I was lucky if they stayed up without the help of a belt!

Monday I am digging out "goal pants" which was favorite pair of Old Navy pants I had before I got pregnant (I think they were size 12) to see if I can wear them again.
Even if I can't fit into them completely...I know I'm closer to fitting into them than I was 6 months ago.
