Zeppelin Black Velvet Flares

I loved my first pair of these, and I needed a different size when ordering a second pair after pregnancy. I made many attempts to get in contact to enquire about sizing and never heard back. I measured as an XL, bought a L and it was too big around the waist and keeps falling down. The rise on the front is lower (mid-rise) than my previous pair (size S) which sat at my navel. Disappointed with the service and the fit.
