I’ve lost some weight. Off the thighs/hips not the tummy. Would love a tartan/checked skirt, just above the knee. Tried on a couple today, but size 12 is tight on tummy good on hips, but 14 is good on tummy sticks out on hips. Is there a Lycra type alternative? Google gives me really mini ones. But I’m over 50, and have never been a mini person. TIA
