Ultra Flirt Womens London Sweater

Darling red knit sweater with "London" across the front in black. Black and white stripes on the sleeves. Label reads: Ultra Flirt, and there's a size tag of medium. Do see the measurements below though. Non contents tag but it feels like an acrylic maybe.
Excellent preowned condition, one of two small snags in the knit and some mild pilling.

Measurements taken flat and doubled round bust and waist.
armpit to armpit across bust: 50" at rest to about 66" stretched
waist: 35" to 54"
length shoulder seam to bottom: 24.5"
