Sorry for the slow reply -- yesterday was a travel day and I just didn't have it in me!!
Zaeobi -- I just tuck a teeny portion of a sweater into the front of the waistband -- you can't really see the bit of added bulk because the sweater blouses over at the front and drops lower in the back. Plus, I don't really have a waist worth featuring, so this helps to give the illusion of waist.
Jules -- waving at my cool girl sweatpants twin!!!... Your daughter's comment made me giggle. I'm sure I'm older than you, so I wonder what it means for someone MY age to like them!!?? In any case, I do. A lot.
Jenni --good stories!!!
