Most of my pants are size 2P (Gap/Old Navy) or 3 in Jrs. (Union Bay) but wanting these in a more comfortable fit I ordered 4S.  When I tried them on I couldn't believe it, they were so tight I had to hold my breath to button them.  So, I returned them for a 6, a size I haven't worn since I lost weight 15 years ago.  Once that was straightened out, I have jeans that fit well all over instead of the usual too tight in some places and too big in others.  A little spandex helps them move with you comfortably, but they don't stretch out or lose their shape.

The limitless wash had weird zebra stripes around the hips that make the jeans look permanently rumpled and draw attention to your widest part. The label in the back of the waist band was scratchy and irritating so I used a seam ripper to take it out.  Being only 5ft, they are still too long for me, but that isn't usual.
