Aritzia silk chiffon cropped camisole

Not a halter but similar effect (cannot find the right word for this neckline, tell me if you know it!) narrower at the back. Zig-zag cut along the bottom (raw) edge. Outside is silk with a silky poly lining. I mended the strap on one side but it’s not noticeable (I included a photo). The color is sort of a purplish grey.
