Go!
Hang on, more info. Must be available online from reputable sellers who have size guides one can trust. My waist is 86-87 cm, my hips 110/111 or so. Nothing too flimsy or thin single-layer jersey, it just shows off my flesh ruffles.
I'm looking madly and find nothing. Prefer midi lengths, i.e. 65-75 cm. There's a challenge!
(incidentally I'm not very hourglassy, but judging by the way clothes are cut these days I'm like Joan from Mad Men apparently)
