A velvet skirt with elastic waist.
The fabric is a 'burn-out' or 'devore' velvet which makes it feel like silk, with little areas where the velvet pile has been removed, so its a perfect textile to wear in all climates.
Skirt lining finishes at the top of front and back slits. These slits enable you to walk easily and have a flash of ankle/calf as you move.
Sizing, well the side panels are bias cut which means they're stretchy. Mel wears M/L in this style.
