Ponte Bell Bottom Pant

I loved my old Blue Canoe bell-bottom yoga pants, and I wore them so much that after 5 or 6 years they are starting to fall apart. Tried to replace them with these, but it's not working for me. I don't care for the ponte fabric--it feels like it doesn't breathe well, and it's way too stretchy. I usually wear a medium in most pants, but in yoga pants I always get a small b/c they stretch. These are a small, and right out of the bag the crotch is so stretchy that it's sagging--very unflattering. The legs also feel too stretchy, like they will stretch out and not stay up. I really don't like the waistband--it's just fabric folded over elastic, and it's not stitched in place. There's just a little stiching at the front and back, and nowhere else. Right out of the bag, the waistband is already folding over, the elastic is twisting, and it feels uncomfortable. Please bring back the old bell-bottoms, in the old great-quality cotton, with the old waistband.
