Colorfulkoala Women's Buttery Soft High Waisted Yoga Pants 7/8 Length Leggings

These used to be matte, soft, and they didn’t budge. Now they are slick, shiny, and roll. Any recommendations for a new brand?

Do these leggings have a flat waistband, or do they have a thin band of elastic at the top of the waistband?

Do these leggings have Draw string in the waists hand to make them tighter?

Where are these pants made?
