Devoid of side-seams, the fabric to be used for this waist-jacket will have it’s weft aligned with the (missing) sideline, making it fall in partial bias towards the front and central-back-seam, exhibiting, with an appropriate choice of fiber, a sideways diverging look.
More perceptible, however, might be the extravagant hemline presented by both body and sleeves, traversing downwards in a motion concave in the front, yet ending cuspy in the back.
Adorning this effect, while supplying a sense of changeability are the invisible zippers mounted in the jacket’s sleeves, going up all the way through the shoulder-line, making them, just like the jacket itself, able to be worn open or closed.
The complementary skirt-thingy shown in the sketch is not an actual part of the design, but rather a matching accessory for saturday’s outfit.
