This is a lovely Ben Zuckerman jacket, probably part of a skirt in a grey- beige. It probably dates from the mid 1950's, and is a slightly more relaxed style for a Zuckerman. It features large buttons and a bow tie and the neck to add a feminine touch. The material of the jacket is a 'waffley' style, almost like seersucker and I would guess that this is a summertime look.
