Women’s vintage sweater by British Vogue. Buttery yellow. Unsure of size S or M

Nana chic vintage sweater ( 1960s?) by British Vogue, Inc. No tag stating size. Guesstimating S to M. 100% acrylic. Scalloped at bottom of sleeves & body of sweater. A little pilling on lower sleeves. One small snag on left sleeve pictured in next to last photo. All in all, great shape for its age. Cute swirly yellow buttons to boot!
