ColorfulkoalaWomen's High Waisted Joggers with Pockets Full Length Sweatpants & Lounge Pants

How stretchy are the bottoms of these? i just had knee surgery and need pants that i can wear to pt and roll up above my knee.

I’m 5’1” and 150 and normally wear small in joggers. What size should I get?

If I’m 5’6.5” and weight about 130-135 what size should I get? Small or medium?

do these suck your waist in like high waisted leggings do?
