VTG White Grandma Button-Up Knit Cardigan

Vintage from Haband. White knit Button-Up cardigan. Pearlized buttons. Slight flaw as there is some gaping when it is fully buttoned (see pic). Otherwise in excellent condition. No stains, holes, or pulls. Unfortunately I do not have a size or material tag either. See measurements for best fit. Approximate Measurements: 22" pit to pit 29" long 26" sleeves
