Striped silk taffeta in black and pearl gray with narrow 1/8" crosswise stripes in black and cool gray. I would probably cut this on the cross grain so the stripes/yarns run vertically, but you could also cut on the lengthwise grain or bias. Silky smooth and lightly crisp with a malleable hand and airy drape. Light weight and lightly crisp dress it up or down, make a dress, shirt, skirt, vest, duster coat, sculptural airy pants.

Dry clean or hand launder and air dry. I sometimes toss silk taffeta in the washer/dryer, which makes it a bit more cotton-y, this kicks back the silky shine and creates lovely all-over crinkles. I take it out of the dryer when it is just a bit damp, smooth it out, give a light press. You can then sew and press as usual, and it will retain the soft crinkles. Always test a swatch first to be sure you like the results.
After sewing, hand launder or machine wash gentle, while damp, pull out and smooth the edges - I would not put it in the dryer again once the garment is sewn.
