From J. Crew:
Soft cotton-blend micro-tweed that we developed to be incredibly lightweight with a hint of stretch. Tailored detailing like a close fit and a hidden two-way zip combines with the easy knit fabric to create a versatile piece we're wearing with high heels and dresses on Monday and jeans and flats for weekend brunch.
