Royal Purple and Black Ponte Knit Stripe detail

Highly desirable royal purple and black crosswise stripe in a beautiful quality ponte knit. This is a REALLY nice quality ponte, with 4 way stretch and a lovely selvedge. For a top, T, cardi, even a soft pant (cut on the cross wise so the strips run up and down).
