I feel ya on that, Betty! Some solutions I've found -
Rag & Bone printed sweatpant jeans - I don't wear these to work but they are great for the weekends. Nobody realizes they are sweatpants.
Betabrand yoga pants - look like dress pants but are stretchy and feel like yoga pants.
LOFT ponte knit 5 pocket pants - these are not flowy, so YMMV, but they are stretchy and I am practically living in them lately. My go-to for business travel.
I just got a BR dress like this, but it's in midi length - which will look cute with flat booties:

Shift style dresses are another favorite.
VC tube skirts are awesome.
EF slouchy pants. For winter, try their merino version:

I bought a pair in merino, they were much too big & baggy, the waist came up to under my rib cage, they were also too long.... but SO incredibly comfortable, so soft against the skin, so cozy and warm... I kept them for loungewear/sleepwear!!! I have been wearing them around the house constantly. Then my hubby accidentally sent them through the wash and dryer (I think they are supposed to be dry clean?). And they shrunk. To PERFECT size! So I will be wearing these out of the house now, for sure...
