Finishing a non-standard hemline, like the concave form on the Slanted Jacket works best when it is stitched off with a likewise-cut strip of the same material, having the actual lining sewn to it with a medium backstitch afterwards.
Apart from obtaining the projected hemline, the addition of the facing-strip comes with some extra dexterity, in this particular case enhancing the pelt-ish intent of the bolero-jacket, unfortunately non-adaptable to the basque-like skirt-appendage for the lower-garment-friction it would bring.
When working with fur-like fabrics, a satin lining is always the way to go ^_^
