I have always had a very tough time finding jeans - I am (relatively) small in the hips and thighs and butt, but big in the waist so anything that fits in the waist is too big everywhere else.
When I lost about 40 lbs a couple of years ago, along the way, I found a pair of size 16 jeans that worked. I can't remember exactly what weight I was when I bought them, but I was very excited to wear them, and they even got a little bit too big on me before I started gaining it all back. Today, they finally fit again!!
I have a couple of other pairs, also size 16 but much smaller and no spandex, so that will be a HUGE victory when those fit, that's still a ways off - they never fit even with the 40 lbs the last so I know it will be a while. But I'm still very happy to get back into the ones that fit again right now - it's nice to have at least one pair of jeans that I can wear!
