Fabulous Vintage Fashion Designer Dan Millstein for B. Altman White Vest

What a fun and fabulous high end vintage piece by Dan Millstein for B. Altman Department Store. Great texture (see close-up) and wonderful big buttons- with extra button still intact. No size tag but I would estimate a Large- plenty of room for chic layering! Slits / side vents and two patch pockets on front. Measures approximately 24” flat armpit to armpit and approximately 22.5” armpit to hem. Very good vintage condition. I love offers!
