I'm a fan, but I have to be careful how I dress in them. Because of my wide hips, they can look awful on me.
I've seen everal well combined looks in store windows. Unusally the Maxi skirt itself has to be sharp, have a nice texture (no slimsy material). Waist high, combined with a nice blouse and an oversized wool cardigan it can look nice.
On the rigt body ofc....
