Retro mod 1950s 6190s handmade nylon V-neck sleeveless tank top in hot pink and white. I see this top tucked into cigarette pants, or worn loose with jeans or pencil pants. Deep v-neck. Cut in a boxy shape that can be crop-length depending on how you wear it. No size or material tag, so see measurements. I estimate a size 4, though it has stretch and can be sized up or down depending on what you're looking for. EVC.

Flat lay measurements:
Length: 21"
Pit to pit: 20. 25
Width: 22"

This item is sold from an excellent, highly rated vintage boutique in Charlottesville, VA.
