Vintage 70s 4pc Mix Match Set Pants Tank Shirt Turtleneck XS

Vintage 70s 4pc mix and match set including pants, back zip turtleneck and shell with coordinating pointy collar button up shirt. I am not open to separating the set at this time. The pants are 100% polyester pull on style with wider straight leg. Laying flat the pants measure 11” straight across the waist relaxed stretching to 14” without much resistance. 28.5” inseam. 16.5” across the hip and 11” across the leg opening. No brand name. The shell and button up shirt can be worn together or separately. The sleeveless tank measures 21.5” shoulder to hem and 15” armpit to armpit. The button up has a pointy collar and measures 23” shoulder to hem and 16” armpit to armpit. There are a couple pin sized holes at the shoulder seam. Finally, the turtleneck is stretchy 100% nylon and zips at the back neck. Tag size medium measuring 23” shoulder to hem and 17” armpit to armpit.
