A turtleneck crop top is a shirt that covers the neck while leaving the stomach bare, thus it should imply related tags. I don't think it's a bad tag, even if it's small - while it is a composite tag in theory, shirts that are both of those things at once feel a bit more "unique" than both elements separately.
I'm not sure if we need the triple composite tag of sleeveless turtleneck crop top, but since it exists, I decided to not skip it. I wouldn't exactly be against nuking it, though.
